+# Polymer Element Catalog
+
+## Getting Started
+
+To work on the Polymer Elements Catalog, clone the repository.
+
+To install dependencies:
+
+    npm run deps
+    
+To start a local development server:
+
+    npm run serve
+    
+To start a local development server with `fixtures` turned on:
+
+    FIXTURES=true npm run serve
+    
+To prepare the repo for publication:
+
+    npm run build
+    
+Note: Make sure that you're running chrome 42 or later!
+    
+### Fixtures
+
+While parts of the system are still in flux, it will be necessary to have stubbed
+data and other bits to be able to work against. Anything in the `fixtures`
+directory will be available when running a development server. By the time
+the catalog ships, the `fixtures` directory should be empty.
+
+## Managing Catalog Data
+
+Data for the catalog is compiled by intelligently composing together information
+from multiple sources:
+
+1. The `catalog.json` file in this repository
+2. The `bower.json` for each element package and individual element
+3. Metadata parsed directly elements' source using [hydrolysis](https://github.com/PolymerLabs/hydrolysis)
+4. Other files in package and element repositories, such as guide markdown files
+
+Each of these inputs is combined and compiled into a static format easily loaded
+by the catalog application. Outputs of the catalog compilation process include:
+
+1. A `/data/catalog.json` file heavily annotated with parsed metadata
+2. Pre-parsed element documentation in `/data/docs`
+3. The compiled HTML output of guide markdown files in `/data/guides`
+
+### How `catalog.json` is Created
+
+The final `catalog.json` file can be thought of as the repo's initial file
+decorated substantially with metadata. For instance, a package in the initial
+file:
+
+```json
+{
+  "packages": [
+    {"title":"Iron Elements", "name":"iron-elements"}
+  ]
+}
+```
+
+Gets decorated with metadata parsed from its' `bower.json`:
+
+```json
+{
+  "packages": [
+    {
+      "title":"Iron Elements",
+      "name":"iron-elements",
+      "description":"Polymer core elements",
+      "version":"1.0.0",
+      "tags":["utility","scaffolding","user-input"]
+    }
+  ]
+}
+```
+
+This decoration occurs in steps and can be considered a series of merges.
+
+### Packages
+
+Each set of elements (henceforth "package") is responsible for maintaining its
+own documentation according to the conventions established elsewhere in this
+document. Each package is represented in `catalog.json` as an entry in an array.
+This array corresponds to the order in which packages are presented in nav
+contexts in the element catalog. Each package has the following associated data:
+
+* **name:** the corresponding package name from `bower.json`
+* **title:** the human-friendly name of the package for nav display
+
+Each named package should be declared as a dependency in the `bower.json` for
+this repository. Additionally, each package's version number should be explicit,
+as the version declared in `bower.json` is used as display text in the catalog.
+
+```js
+{
+  // correct example
+  "iron-elements":  "PolymerElements/iron-elements#1.0.0"
+  // incorrect example
+  "paper-elements": "PolymerElements/paper-elements#^1.0"
+}
+```
+
+By maintaining strict versioning in the catalog, updating a package's data
+becomes as easy as a pull request to `bower.json`.
+
+### Package Metadata
+
+As much as possible, the element catalog uses existing conventions from systems
+such as Bower as a repository for metadata.
+
+#### bower.json
+
+The `bower.json` for a package should contain a `dependencies` entry for each of
+its child elements. A declared dependency will be considered a child element of
+the package if and only if its name is identical to the package name before the
+first dash. As an example, if the package is `iron-elements`, `iron-ajax` would
+be considered a child but `polymer` would not.
+
+The element catalog uses the following information from `bower.json`:
+
+* **name:** The package name should correspond to a `packages` entry in the
+  `catalog.json` file in this repository for it to be displayed.
+* **description:** The package description should be phrased such that it can
+  be used as descriptive summary text in the catalog when the package is
+  presented along-side other packages. It should be less than 200 characters
+  in length but adequately descriptive of the primary use cases for the package.
+* **keywords:** Excluding `web-components` and `polymer`, these keywords will be
+  used as **tags** in the final catalog data.
+
+### Elements
+
+Elements behave much like packages: they are responsible for maintaining their
+own documentation in `bower.json`. In addition, the source `.html` files for
+elements should be documented in accordance with the [Polymer Elements style guide](http://polymerelements.github.io/style-guide/).
+
+#### bower.json
+
+The catalog uses the following information from an element's `bower.json`:
+
+* **name:** The element name. Except in rare cases, this should match a `.html`
+  file of the same name that contains the element or imports all default elements
+  for element repos with multiple elements.
+* **description:** A less-than-200 character description of what the element
+  does and how it should be used.
+* **keywords:** Except for `web-components` and `polymer`, these keywords will
+  be used as **tags** in the final catalog data.
+* **main:** This field should represent **every .html file that a user might
+  directly import**. For instance, in `iron-icons` each icon set might be imported
+  separately, so each set should be included in main. For many (most) elements
+  this can just be a string with the `.html` filename matching the `name` field.
+
+### Guides
+
+Guides are in-depth articles that allow for article-style documentation in
+addition to the API documentation for each element parsed using hydrolysis.
+
+Guides are simply Markdown files with YAML front-matter and can be included
+in the repository for the catalog, a package, or an individual element. To
+avoid namespace collisions, guides for packages and individual elements are
+identified with `repo-name/guide-name`, while guides in this repository are
+identified simply with `guide-name`.
+
+Each guide will be listed and accessible in the **Guides** section of the
+catalog, and will additionally be associated with each element and package
+it references.
+
+#### Example Markdown File (e.g. `bower_components/gold-elements/guides/ecommerce.md`)
+
+```markdown
+---
+title: How to Build an E-Commerce Site with Gold Elements
+summary: "Learn how to add drop-in E-commerce components to quickly build a web presence for your business."
+tags: ['ecommerce','beginner']
+elements: ['gold-checkout','paper-input']
+updated: 2015-04-10
+---
+
+Actual article content starts here.
+
+## Example Section
+
+Etc. etc.
+```
+
+#### Example compiled `catalog.json`
+
+```js
+{
+  // guides with associated packages should also be referenced in the package metadata
+  "packages": [
+    {"name":"gold-elements","guides":["gold-elements/ecommerce"]}
+  ],
+  "guides": [
+    {
+      "name":"gold-elements/ecommerce",
+      "title":"How to Build an E-Commerce Site with Gold Elements",
+      "tags":["ecommerce","beginner"],
+      "elements":["gold-checkout","paper-input"],
+      "package":"gold-elements"
+    }
+  ],
+  "elements": [
+     {"name":"paper-input","guides":["gold-elements/ecommerce"]}
+  ]
+}
+```
+
+#### Assets in Guides
+
+If a guide needs images or other assets, those should be stored in `/guides/assets`
+in the repository and always referenced with relative URLs (e.g. `assets/filename.jpg`).
+By maintaining this convention the catalog compilation process will automatically
+ensure that images and other assets are properly accessible to the guide.

+
+## Overview
+
+The `iron-flex-layout` component provides simple ways to use [CSS flexible box layout](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes), also known as _flexbox_. This component provides two different ways to use flexbox:
+
+*   Layout classes. The layout class stylesheet provides a simple set of class-based flexbox rules. Layout classes
+    let you specify layout properties directly in markup.
+
+*   Custom CSS mixins.  The mixin stylesheet includes custom CSS mixins that can be applied 
+    inside a CSS rule using the `@apply` function. 
+
+Using the classes or CSS mixins is largely a matter of preference. The following sections discuss 
+how to use the each of the stylesheets.
+
+<aside><b>Note:</b> Before using either of these stylesheets, it's helpful to be familiar with the basics 
+of flexbox layout. Chris Coyier's [A Complete Guide to Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/) is a 
+good primer.</aside>
+
+### Using layout classes
+
+To use layout classes import the `classes/iron-flex-layout` file.
+
+    <link rel="import" href="bower_components/iron-flex-layout/classes/iron-flex-layout.html">
+
+Then simply apply the classes to any element.
+
+    <div class="layout horizontal wrap">
+
+Many of the layout rules involve combinations of multiple classes (such as `layout horizontal wrap` above).
+The order in which the classes are specified doesn't matter, so `layout horizontal` and `horizontal layout`
+are equivalent.
+
+_Currently_, the layout class stylesheet uses the `/deep/` combinator 
+and therefore, works across all local DOM boundaries. 
+
+Because `/deep/` is slated to be removed from the shadow DOM spec, this
+stylesheet will eventually be replaced by a  set of rules that do not use
+`/deep/`. When that happens, the stylesheet will need to be imported into each
+scope  where it's used.
+
+### Using layout mixins
+
+Custom mixins can be applied inside a Polymer 
+custom element's stylesheet, **or** inside a `custom-style` stylesheet to apply styles to the 
+main document. (They cannot be applied in the main document without a `custom-style` stylesheet.)
+
+**Example: using mixins in the main document**
+
+    <head>
+
+      ...
+
+      <link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout.html">
+
+      ...
+
+      <!-- main document -- apply mixins in a custom-style element -->
+      <style is="custom-style">
+        .container {
+          @apply(--layout-horizontal);
+          @apply(--layout-wrap);
+        }
+      </style>
+
+    </head>
+    <body>
+
+      <div class="container">
+        <div>One</div>
+        <div>Two</div>
+        <div>Three</div>
+      </div>
+
+    </body>
+
+**Example: using mixins in a Polymer element**
+
+    <link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout.html">
+
+      ...
+
+    <dom-module id="mixin-demo">
+
+      <!-- inside an element -- apply mixins in a standard style element -->
+      <style>
+        .container {
+          @apply(--layout-horizontal);
+          @apply(--layout-wrap);
+        }
+      </style>
+
+      <template>
+        <div class="container">
+          <div>One</div>
+          <div>Two</div>
+          <div>Three</div>
+        </div>
+      </template>
+
+      <script>
+        Polymer({ is: 'mixin-demo' });
+      </script>
+
+    </dom-module>
+
+
+In general the mixins require a little more code to use, but they can be preferable if you
+don't want to use the classes, or if you want to switch layouts based on a media query.
+
+Custom CSS properties and mixins are features provided by the Polymer library. 
+See [Cross-scope styling](https://www.polymer-project.org/1.0/docs/devguide/styling.html#xscope-styling) 
+in the Polymer developer guide.
+
+## Horizontal and vertical layout
+
+Create a flex container that lays out its children vertically or horizontally.
+
+Class | Mixin | Result 
+:-|:-|:-
+<code>layout horizontal</code>| <code>&#8209;&#8209;layout-horizontal</code> | Horizontal layout container.
+<code>layout vertical</code> | <code>&#8209;&#8209;layout-verical</code> | Vertical layout container.
+
+**Example: classes** 
+
+    <div class="layout horizontal">
+      <div>One</div>
+      <div>Two</div>
+      <div>Three</div>
+    </div>
+
+**Example: mixins** 
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-horizontal);
+        }
+      </style>
+
+      <template>
+
+        <div class="container">
+          <div>One</div>
+          <div>Two</div>
+          <div>Three</div>
+        </div>
+
+        ...
+
+**Example output**
+
+<div class="layout horizontal demo">
+  <div>One</div>
+  <div>Two</div>
+  <div>Three</div>
+</div>
+
+### Flexible children
+
+Children of a flex container can use flex to control their own sizing.
+
+Class | Mixin | Result 
+:-|:-|:-
+<code>flex</code>| <code>&#8209;&#8209;layout-flex</code> | Expand the child to fill available space in the main axis.
+<code>flex-<var>ratio</var></code>| <code>&#8209;&#8209;layout-flex-<var>ratio</var></code> | Assign a flex ratio of 1 to 12.
+<code>flex-none</code>| <code>&#8209;&#8209;layout-flex-none</code> | Don't flex the child.
+<code>flex-auto</code>| <code>&#8209;&#8209;layout-flex-auto</code> | Sets flex `flex-basis` to `auto` and `flex-grow` and `flex-shrink` to 1.
+
+
+**Example: classes** 
+
+        <div class="horizontal layout">
+          <div>Alpha</div>
+          <div class="flex">Beta (flex)</div>
+          <div>Gamma</div>
+        </div>
+
+**Example: mixins** 
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-horizontal);
+        }
+        .flexchild {
+          @apply(--layout-flex);
+        }
+      </style>
+
+      <template>
+
+        <div class="container">
+          <div>One</div>
+          <div class="flexchild">Two</div>
+          <div>Three</div>
+        </div>
+
+        ...
+
+**Example output**
+
+<div class="horizontal layout demo">
+  <div>Alpha</div>
+  <div class="flex">Beta (flex)</div>
+  <div>Gamma</div>
+</div>
+
+#### Flexible children in vertical layouts
+
+The same rules can be used for children in vertical layouts.
+
+**Example: classes**
+
+    <div class="vertical layout" style="height:250px">
+      <div>Alpha</div>
+      <div class="flex">Beta (flex)</div>
+      <div>Gamma</div>
+    </div>
+
+**Example: mixins**
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-vertical);
+        }
+        .flexchild {
+          @apply(--layout-flex);
+        }
+      </style>
+
+      <template>
+
+        <div class="container">
+          <div>One</div>
+          <div class="flexchild">Two</div>
+          <div>Three</div>
+        </div>
+
+        ...
+
+**Example output**
+
+<div class="vertical layout demo tall">
+  <div>Alpha</div>
+  <div class="flex">Beta (flex)</div>
+  <div>Gamma</div>
+</div>
+
+**Note**: for vertical layouts, the container needs to have a height for the 
+children to flex correctly.
+
+#### Flex ratios
+
+Children elements can be told to take up more space by including a "flex ratio"
+from 1 to 12. This is equivalent to specifying the CSS `flex-grow` property.
+
+For example, the following examples make "Gamma" 2x larger than "Beta" and "Alpha" 3x larger, use 
+`flex-2` and `flex-3`, respectively.
+
+**Example: classes**
+
+        <div class="horizontal layout demo">
+          <div class="flex-3">Alpha</div>
+          <div class="flex">Beta</div>
+          <div class="flex-2">Gamma</div>
+        </div>
+
+**Example: mixins**
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-horizontal);
+        }
+        .flexchild {
+          @apply(--layout-flex);
+        }
+        .flex2child {
+          @apply(--layout-flex-2);
+        }
+        .flex3child {
+          @apply(--layout-flex-3);
+        }
+      </style>
+
+      <template>
+
+        <div class="container">
+          <div class="flex3child">One</div>
+          <div class="flexchild">Two</div>
+          <div class="flex2child">Three</div>
+        </div>
+
+        ...
+
+**Example output**
+
+<div class="horizontal layout demo">
+  <div class="flex-3">Alpha</div>
+  <div class="flex">Beta</div>
+  <div class="flex-2">Gamma</div>
+</div>
+
+<!--
+### Auto-vertical
+
+For vertical layouts, you can use the `auto-vertical` attribute
+on a child element to set an automatic flex basis on that element.
+Use this attribute for responsive designs
+if you want elements laid out horizontally when the display is wide
+or vertically when narrow.
+
+The following code uses `core-media-query` to get the screen size.
+If it's smaller than 640 pixels,
+the layout becomes vertical and the elements layout on a flex basis.
+Otherwise, the layout becomes horizontal and the elements are laid out
+normally.
+
+{% raw %}
+    <template is="auto-binding">
+      <core-media-query query="max-width: 640px"
+                        queryMatches="{{phoneScreen}}"></core-media-query>
+      <div layout vertical?="{{phoneScreen}}"
+           horizontal?="{{!phoneScreen}}">
+        <div auto-vertical>Alpha</div>
+        <div auto-vertical>Beta</div>
+        <div auto-vertical>Gamma</div>
+      </div>
+    </template>
+{% endraw %}
+
+<div vertical layout class="demo" style="height:170px">
+  <div auto-vertical>Alpha</div>
+  <div auto-vertical>Beta</div>
+  <div auto-vertical>Gamma</div>
+</div>
+-->
+
+### Cross-axis alignment
+
+By default, children stretch to fit the cross-axis (e.g. _vertical_ stretching in a _horizontal_ layout).
+
+    <div class="horizontal layout">
+      <div>Stretch Fill</div>
+    </div>
+
+<div class="horizontal layout demo tall">
+  <div>Stretch Fill</div>
+</div>
+
+Center _across_ the main axis (e.g. _vertical_ centering elements in a _horizontal_ layout)
+by adding the `center` class or applying the `--layout-center` mixin.
+
+**Example: classes, cross-axis center**
+
+    <div class="horizontal layout center">
+      <div>Center</div>
+    </div>
+
+**Example: mixins, cross-axis center**
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-horizontal);
+          @apply(--layout-center);
+        }
+      </style>
+
+      <template>
+
+        <div class="container">
+          <div>Center</div>
+        </div>
+

+
+You can also position at the top/bottom (or left/right in `vertical` layouts) using the `start` or `end`
+classes, or by applying the `--layout-start` or `--layout-end` mixins.

+### Justification
+
+Justifying aligns contents along the **main axis**.  Justify the layout 
+by specifying  one of the following.
+
+
+Class | Mixin | Result 
+:-|:-|:-
+`start-justified`| <code>&#8209;&#8209;layout-start-justified</code> | Aligns contents at the start of the main axis.
+`center-justified` | <code>&#8209;&#8209;layout-center-justified</code> | Centers contents along the main axis.
+`end-justified` | <code>&#8209;&#8209;layout-end-justified</code> | Aligns contents to the end of the main axis.
+`justified` | <code>&#8209;&#8209;layout-justified</code> | Aligns contents with equal spaces between children. 
+`around-justified` | <code>&#8209;&#8209;layout-around-justified</code> | Aligns contents with equal spaces arround children. 
+
+
+
+**Example: classes, start justified** 
+

+
+## Self alignment
+
+Alignment can also be set per-child (instead of using the layout container's rules).
+
+Class | Mixin | Result 
+:-|:-|:-
+`self-start`| <code>&#8209;&#8209;layout-self-start</code> | Aligns the child at the start of the cross-axis.
+`self-center` | <code>&#8209;&#8209;layout-self-center</code> | Centers the child along the cross-axis.
+`self-end` | <code>&#8209;&#8209;layout-self-end</code> | Aligns the child at the end of the cross-axis.
+`self-stretch` | <code>&#8209;&#8209;self-stretch</code> | Stretches the child to fit the cross-axis. 
+
+**Example: classes**
+
+    <div class="horizontal layout" style="height: 120px;">
+      <div class="flex self-start">Alpha</div>
+      <div class="flex self-center">Beta</div>
+      <div class="flex self-end">Gamma</div>
+      <div class="flex self-stretch">Delta</div>
+    </div>
+
+**Example: mixins**
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-horizontal);
+          @apply(--layout-justified);
+          height: 120px;

+  <div class="flex self-center">Beta</div>
+  <div class="flex self-end">Gamma</div>
+  <div class="flex self-stretch">Delta</div>
+</div>
+
+<aside><b>Note:</b> The <code>flex</code> class 
+(and <code>--layout-flex</code> mixin) shown in these examples is
+added for the demo and not required for self-alignment.</aside>
+
+
+## Wrapping
+
+Wrapped layouts can be enabled with the `wrap` class or `--layout-wrap` mixin.
+
+**Example: classes**
+
+    <div class="horizontal layout wrap" style="width: 220px">
+      <div>Alpha</div>
+      <div>Beta</div>
+      <div>Gamma</div>
+      <div>Delta</div>
+    </div>
+
+**Example output**
+
+<div class="horizontal layout wrap demo" style="width: 220px">
+  <div>Alpha</div>
+  <div>Beta</div>
+  <div>Gamma</div>
+  <div>Delta</div>
+</div>
+
+## Reversed layouts
+
+Layout direction can be mirrored using the following rules:
+
+Class | Mixin | Result 
+:-|:-|:-
+<code>layout horizontal&#8209;reverse</code>| <code>&#8209;&#8209;layout-horizontal-reverse</code> | Horizontal layout with children laid out in reverse order (last-to-first).
+<code>layout verical&#8209;reverse</code> | <code>&#8209;&#8209;layout-verical-reverse</code> | Vertical layout with children laid out in reverse order.
+<code>layout wrap&#8209;reverse</code> | <code>&#8209;&#8209;layout-wrap-reverse</code> | Wrap layout with wrapped rows placed in the reverse order (for example, in a vertical layout, the second row is placed above the first row, instead of below).
+
+**Example: mixins**
+
+    <dom-module id="mixin-demo">
+
+      <style>
+        .container {
+          @apply(--layout-horizontal-reverse);
+        }
+      </style>
+
+      <template>
+
+        <div class="container">
+          <div>Alpha</div>
+          <div>Beta</div>
+          <div>Gamma</div>
+          <div>Delta</div>
+        </div>
+
+        ...
+
+**Example output**
+
+<div class="horizontal-reverse layout demo">
+  <div>Alpha</div>
+  <div>Beta</div>
+  <div>Gamma</div>
+  <div>Delta</div>
+</div>
+
+## Full bleed &lt;body>
+
+It's common to want the entire `<body>` to fit to the viewport. By themselves, Polymer's layout features on 
+`<body>` don't achieve the result. You can make `<body>` take up the entire viewport by adding the `fullbleed` class:
+
+    <body class="fullbleed vertical layout">
+      <div flex>Fitting a fullbleed body.</div>
+    </body>
+
+This removes its margins and maximizes its height to the viewport. There is no equivalent mixin, but the same result can
+be achieved in CSS very simply:
+
+    body {
+      margin: 0;
+      height: 100vh;
+    }
+
+Note that the `fullbleed` class **only works on the `<body>` tag.** This is the only rule in the 
+stylesheet that is scoped to a particular tag.
+
+
+## General purpose rules
+
+Polymer also includes other general purpose rules for basic positioning:
+
+Class | Mixin | Result 
+:-|:-|:-
+`block`| `--layout-block` | Assigns `display: block`
+`invisible` | `--layout-invisible` | Assigns `visibility: hidden`
+`relative` | `--layout-relative` | Assigns `position: relative`
+`fit` | `--layout-fit` | Sets `position: absolute` and sets `top:0;right:0;bottom:0;left:0;` (aka "trbl fitting"). 
+
+<aside><b>Note:</b>When using `fit` layout, the element must have an ancestor with fixed size and `position: relative` layout
+to fit inside of.
+</aside>
+
+
+**Example: classes**
+
+    <div>Before <span>[A Span]</span> After</div>
+
+    <div>Before <span class="block">[A Block Span]</span> After</div>
+    <div>Before invisible span <span class="invisible">Not displayed</span> After invisible span</div>
+    <div class="relative" style="height: 100px;">
+      <div class="fit" style="background-color: #000;color: white">Fit</div>
+    </div>
+
+**Example output**
+
+<div class="demo">Before <span>[A Span]</span> After</div>
+<div class="demo">Before <span class="block">[A Block Span]</span> After</div>
+<div class="demo">Before invisible span <span class="invisible">Not displayed</span> After invisible span</div>
+<div class="relative" style="height: 100px;" class="demo">
+  <div class="fit" style="background-color: #000;color: white">Fit</div>
+</div>

+
+## Introduction
+
+This guide teaches you how to use Paper and Iron elements to create a 
+responsive layout.
+
+## Installation
+
+Below is a list of commands for installing all of the elements mentioned
+in this document. You probably
+do not need to install all of these elements. Read the guide and decide
+how you want to implement your layout, and then install only the elements
+that you need.
+
+```bash
+bower install --save PolymerElements/paper-header-panel
+bower install --save PolymerElements/paper-toolbar
+bower install --save PolymerElements/paper-drawer-panel
+bower install --save PolymerElements/paper-icon-button
+bower install --save PolymerElements/paper-tabs
+bower install --save PolymerElements/paper-tab
+bower install --save PolymerElements/iron-icons
+bower install --save PolymerElements/iron-flex-layout
+```
+
+We'll assume that you can import these elements from `/bower_components/`.
+
+## Creating a header
+
+This section shows you how to:
+
+* Create a standard layout with `paper-header-panel` and `paper-toolbar`,
+  which is probably the most common and easiest layout.
+* Use a custom element for a header.
+* Add icons to a header.
+* Set the height of a header.
+* Add tabs to a header.
+* Modify the disply and behavior of a header.
+
+### Creating a header with `paper-toolbar`
+
+The code below uses a `paper-header-panel` as the container of the
+page and a `paper-toolbar` as a header. When a `paper-toolbar` is a 
+child of `paper-header-panel`, the panel automatically displays 
+the toolbar as the header. All other 
+children are placed in the content area.
+
+```hmtl
+...
+<head>
+...
+  <link rel="import" 
+        href="/bower_components/paper-header-panel/paper-header-panel.html">
+  <link rel="import" 
+        href="/bower_components/paper-toolbar/paper-toolbar.html">
+  <link rel="import" 
+        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
+...
+<body class="fullbleed vertical layout">
+  <!-- paper-header-panel must have an explicit height -->
+  <paper-header-panel class="flex">
+    <paper-toolbar>
+      <div>Header</div>
+    </paper-toolbar>
+    <div>Content</div>
+  </paper-header-panel>
+</body>
+...
+```
+
+<a href="assets/header-and-toolbar.html" target="_blank">
+  <paper-button noink>Demonstration</paper-button>
+</a>
+
+`paper-header-panel` **must have an explicit height**. See the list item
+on `flex` below for an explanation of why the code above works.
+
+`fullbleed`, `vertical`, `layout`, and `flex` are helper classes from
+`iron-flex-layout.html`. We use them in our examples as an easy way 
+to create a responsive design with [Flexbox](http://www.smashingmagazine.com/2015/08/flexible-future-for-web-design-with-flexbox/), 
+but the `paper` elements do not depend 
+on them. Below is a description of each class used in the example above:
+ 
+* `fullbleed` instructs `body` to occupy the entire viewport. 
+* `vertical` and `layout` instruct `body` to stack elements 
+  vertically (use `vertical horizontal` to stack horizontally). `layout`
+  must be accompanied by `vertical` or `horizontal`. It is meaningless
+  on its own.
+* `flex` instructs `paper-panel-header` to stretch to the entire 
+  size of its parent, in this case `body` (which is set to fill the entire 
+  viewport, hence achieving a responsive design).
+
+See [Flexbox layout with iron-flex-layout](/guides/flex-layout) for more
+on `iron-flex-layout`.
+
+### Using other elements for the header
+
+You can use another element as a header by adding the 
+`paper-header` class to the element. 
+
+```html
+<head>
+  <link rel="import" 
+        href="/bower_components/paper-header-panel/paper-header-panel.html">
+  <link rel="import" 
+        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
+...
+<body class="fullbleed vertical layout">
+  <paper-header-panel class="flex">
+    <div class="paper-header">
+      Header
+    </div>
+    <div>Content</div>
+  </paper-header-panel>
+</body>
+```
+
+<a href="assets/custom-header.html" target="_blank">
+  <paper-button noink>Demonstration</paper-button>
+</a>
+
+### Adding icons
+
+Use `paper-icon-button` and `iron-icons` to add icons to your header:
+
+```html
+...
+<head>
+...
+  <link rel="import" 
+        href="/bower_components/paper-header-panel/paper-header-panel.html">
+  <link rel="import" 
+        href="/bower_components/paper-toolbar/paper-toolbar.html">
+  <link rel="import" 
+        href="/bower_components/paper-icon-button/paper-icon-button.html">
+  <link rel="import" 
+        href="/bower_components/iron-icons/iron-icons.html">
+  <link rel="import" 
+        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
+...
+<body class="fullbleed vertical layout">
+  <paper-header-panel class="flex">
+    <paper-toolbar>
+      <div>Header</div>
+      <span class="flex"></span>
+      <paper-icon-button icon="search"></paper-button-icon>
+    </paper-toolbar>
+    <div>Content</div>
+  </paper-header-panel>
+</body>
+```
+
+<a href="assets/icons.html" target="_blank">
+  <paper-button noink>Demonstration</paper-button>
+</a>
+
+`paper-icon-button` displays the icon and handles the icon's behavior.
+`iron-icons` is a collection of SVG icons which you can use for free 
+in your project. 
+
+How does the search icon display on the right side? The trick
+is the `span` between the `div` and the `paper-icon-button`. 
+The `div` containing the text `Header` only takes up as 
+much space as is needed to display 
+the text content. Same with the `paper-icon-button`; it only takes up
+as much space as is needed to display the icon. The `flex`
+class forces the `span` to fill the entire space between the `div` and
+the `paper-icon-button`.
+
+### Setting the height
+
+Use the `medium-tall` (2x regular height) and `tall` (3x regular height) style 
+classes to change the height of your header.
+
+```hmtl
+...
+<head>
+...
+  <link rel="import" 
+        href="/bower_components/paper-header-panel/paper-header-panel.html">
+  <link rel="import" 
+        href="/bower_components/paper-toolbar/paper-toolbar.html">
+  <link rel="import" 
+        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
+...
+<body class="fullbleed vertical layout">
+  <paper-header-panel class="flex">
+    <paper-toolbar class="tall">
+      <div>Header</div>
+    </paper-toolbar>
+    <div>Content</div>
+  </paper-header-panel>
+</body>
+...
+```
+
+<a href="assets/tall-header.html" target="_blank">
+  <paper-button noink>Demonstration</paper-button>
+</a>
+
+### Adding tabs
+
+Use `paper-tabs` to add tabs to your header:
+
+```hmtl
+...
+<head>
+...
+  <link rel="import" 
+        href="/bower_components/paper-header-panel/paper-header-panel.html">
+  <link rel="import" 
+        href="/bower_components/paper-toolbar/paper-toolbar.html">
+  <link rel="import" 
+        href="/bower_components/paper-icon-button/paper-icon-button.html">
+  <link rel="import"
+        href="/bower_components/paper-tabs/paper-tabs.html">
+  <link rel="import" 
+        href="/bower_components/iron-icons/iron-icons.html">
+  <link rel="import" 
+        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
+...
+<body class="fullbleed vertical layout">
+  <paper-header-panel class="flex">
+    <paper-toolbar class="medium-tall">
+      <paper-icon-button id="navicon"
+                         icon="menu"></paper-icon-button>
+      <!-- flex class forces span to fill space between icons -->
+      <span class="flex">Title</span>
+      <!-- icon displays at right because of span class above -->
+      <paper-icon-button id="morebutton"
+                         icon="more-vert"></paper-icon-button>
+      <paper-tabs class="bottom fit" selected="0">
+        <paper-tab>ONE</paper-tab>
+        <paper-tab>TWO</paper-tab>
+      </paper-tabs>
+    </paper-toolbar>
+    <div>Content</div>
+  </paper-header-panel>
+</body>
+...
+```
+
+<a href="assets/tabs.html" target="_blank">
+  <paper-button noink>Demonstration</paper-button>
+</a>
+
+### Modifying header display and behavior
+
+Use the `mode` attribute of `paper-header-panel` to control how the 
+header displays and responds to scrolling. The list below describes 
+the different valid values for `mode`. See the link below for a 
+demonstration of all modes.
+
+* `standard`: The header appears at a higher level than the content area, 
+  with a drop shadow. Content scrolls under the header.
+* `seamed`: The header appears at the same level as the content area, 
+  with a seam between the two (no drop shadow). Content scrolls under the header.
+* `waterfall`: The header initially presents as seamed. When content scrolls 
+  under the header, the header raises up and casts a drop shadow (as in 
+  standard mode).
+* `waterfall-tall`: Like waterfall, except that the toolbar starts off 
+  tall (3x standard height) and condenses to a standard-height 
+  toolbar as the user scrolls. In this mode, `paper-header-panel` controls
+  the height of the toolbar, so you should not set it yourself (via
+  `medium-tall` or `tall`).
+* `scroll`: The header is seamed with the content and scrolls with the content.
+* `cover`: The content scrolls over the header. This mode is designed to 
+  be used with narrow content (for example cards).

+```
+
+<a href="assets/drawer.html" target="_blank">
+  <paper-button noink>Demonstration</paper-button>
+</a>
+
+On narrow screens, the drawer is hidden by default. The user can 
+touch the button or swipe in order to display the drawer.
+On wide screens, the drawer is always open and the button to open
+the drawer is hidden.
+
+Use the `togglePanel` method to hide or reveal the drawer 
+programmatically. Or, add the `paper-drawer-toggle` attribute to an 
+element. This attribute makes the element act as an open / close button and 
+removes the need to call `togglePanel` explicitly.
+
+Any children with the `drawer` attribute set are placed in the navigation area.
+Any children with the `main` attribute are placed in the main panel.

+title: Using Elements
+summary: "Learn how to install and use Polymer Elements in your own projects."
+tags: ['beginner']
+elements: ['paper-checkbox']
+updated: 2015-05-03
+---
+
+
+## Introduction
+
+The Polymer element sets provide elements that you can use in your web pages 
+and apps. These elements are built with the [Polymer library](https://www.polymer-project.org).
+
+**You don't need to use Polymer directly** to use these elements.
+However, using Polymer you can take advantage of special
+features such as data binding.
+
+## Installing Elements
+
+You can install elements one at a time, or install a whole collection of elements.
+
+Polymer contains a few primary collections of elements:
+
+-   [Iron elements](/browse?package=iron-elements). A set of utility
+    elements including generic UI elements (such as icons, input and layout
+    components), as well as non-UI elements providing features like AJAX, signaling and storage.
+
+-   [Paper elements](/browse?package=paper-elements). A set of UI elements that implement the
+    [material design system](http://www.google.com/design/spec/material-design/).
+
+-   [Gold elements](/browse?package=gold-elements). Form elements for ecommerce.
+
+-   [Neon elements](/browse?package=neon-elements). Animation-related elements.
+
+-   [Platinum elements](/browse?package=platinum-elements). Elements for app-like features, 
+    like push notifications, offline caching and bluetooth.
+
+
+If you find a component you want while browsing the docs, simply click the 
+star <iron-icon class="inline-icon" icon="star-border"></iron-icon> to add it to 
+your collection.
+
+When you've selected some components, you can download either a `bower.json` file or a ZIP file.
+
+*   `bower.json` file. Just the metadata you need to install the components using
+    Bower.
+    
+    Bower is the recommended way to manage components. Bower also handles installing
+    the components' dependencies and updating installed components. For more information, 
+    see [Installing with Bower](#installing-with-bower).
+
+*   ZIP file. A single file containing your selected components and all their dependencies, 
+    so you can unzip and start using them immediately. The ZIP file requires no extra tools, 
+    but doesn't provide a built-in method for updating dependencies. For more information, see
+    [Installing from ZIP files](#installing-from-zip-files).
+
+To download the components in your collection:
+
+1.  Click <iron-icon class="inline-icon" icon="stars"></iron-icon> and 
+    select the **Download** tab.
+
+2.  Choose a download format and click **Download**.
+
+Pick your method and follow the instructions in the download dialog.
+
+If you install one or more elements, you also get the
+[Polymer library](https://www.polymer-project.org), as well as the [web components polyfills](http://webcomponents.org/polyfills/),
+which allow you to run Polymer on browsers that don't yet support
+the web components standards.
+
+### Installing with Bower
+
+The recommended way to install **Polymer** elements
+is through Bower. To install Bower, see the [Bower web site](http://bower.io/).
+
+Bower removes the hassle of dependency management when developing or consuming
+elements. When you install a component, Bower makes sure any dependencies are
+installed as well.
+
+#### Project setup
+
+If you haven't created a `bower.json` file for your application, 
+download the `bower.json` from the catalog and edit it to add your
+own project name and version.
+
+If you already have a `bower.json` file, merge the 
+`dependencies` section of the downloaded file into your existing
+`bower.json` file. 
+
+The resulting file should look something like this:
+
+```
+{
+  "name": "my-project",
+  "version": "0.0.0",
+  "dependencies": {
+    "iron-a11y-keys": "PolymerElements/iron-a11y-keys#^1.0.0",
+    "iron-ajax": "PolymerElements/iron-ajax#^1.0.0",
+    "paper-button": "PolymerElements/paper-button#^1.0.0"
+  }
+}
+```
+
+The next step is to install your selected components:
+
+    bower install
+
+Bower adds a `bower_components/` folder in the root of your project and
+fills it with your selected elements and their dependencies.
+
+
+#### Installing from the command line
+
+You can also install components from the command line using the `bower install` command.
+
+You can also choose one of the commonly-used packages:
+
+-   `PolymerElements/iron-elements`
+
+-   `PolymerElements/paper-elements`
+
+-   `PolymerElements/gold-elements`
+
+For example:
+
+    bower install --save PolymerElements/iron-elements
+
+<aside>
+<b>Tip:</b> <code>--save</code> adds the item as a dependency in your app's <code>bower.json</code>.
+</aside>
+
+
+#### Updating packages
+
+When a new version of Polymer is available, run `bower update`
+in your app directory to update your copy:
+
+    bower update
+
+This updates all packages in `bower_components/`.
+
+### Installing from a ZIP file
+
+When you download a component or component set as a ZIP file, you get all of
+the dependencies bundled into a single archive. It's a great way to get
+started because you don't need to install any additional tools.
+
+Expand the ZIP file in your project directory to create a `bower_components` folder.
+
+![Example Zip Contents](assets/zip-file-contents.png)
+
+Unlike Bower, the ZIP file doesn't provide a built-in method
+for updating dependencies. You can manually update components with a new ZIP
+file, or you can update the files using Bower.
+
+#### Migrating from a ZIP file to Bower
+
+If you downloaded a ZIP file and subsequently install Bower, you can
+use `bower init` to create a new `bower.json` file with your existing
+dependencies in it:
+
+    bower init
+
+This generates a basic `bower.json` file. 
+
+Enter **Y** when prompted to set currently installed components as dependencies.
+
+Some of the questions, like "What kind of modules do you expose," can be skipped 
+by pressing Enter.
+
+
+## Using elements
+
+To use elements, first load the web components polyfill library, `webcomponents-lite.min.js`. 
+Many browsers have yet toimplement the various web components APIs. Until they do, `webcomponents-lite`
+provides [polyfill support](http://webcomponents.org/polyfills/). **Be sure to include
+this file before any code that touches the DOM.**
+
+Once you have some elements installed and you've loaded `webcomponents-lite.min.js`,
+using an element is simply a matter of loading the element file using an
+[HTML Import](http://webcomponents.org/articles/introduction-to-html-imports/).
+
+An example `index.html` file:
+
+    <!DOCTYPE html>
+    <html>
+      <head>
+        <!-- 1. Load webcomponents-lite.min.js for polyfill support. -->
+        <script src="bower_components/webcomponentsjs/webcomponents-lite.min.js">
+        </script>
+
+        <!-- 2. Use an HTML Import to bring in some elements. -->
+        <link rel="import" href="bower_components/paper-button/paper-button.html">
+        <link rel="import" href="bower_components/paper-input/paper-input.html">
+      </head>
+      <body>
+        <!-- 3. Declare the element. Configure using its attributes. -->
+        <paper-input label="Your name here"></paper-input>
+        <paper-button>Say Hello</paper-button>
+        <div id="greeting"></div>
+
+        <script>
+          // To ensure that elements are ready on polyfilled browsers, 
+          // wait for WebComponentsReady. 
+          document.addEventListener('WebComponentsReady', function() {
+            var input = document.querySelector('paper-input');
+            var button = document.querySelector('paper-button');
+            var greeting = document.getElementById("greeting");
+            button.addEventListener('click', function() {
+              greeting.textContent = 'Hello, ' + input.value;
+            });
+          });
+        </script>
+      </body>
+    </html>
+
+<aside>
+<b>Note:</b> You must run your app from a web server for the [HTML Imports](http://webcomponents.org/articles/introduction-to-html-imports/)
+polyfill to work properly. This requirement goes away when the API is available natively.
+</aside>
+
+
+If you aren't using the polyfill, you can't rely on the `WebComponentsReady` event. Instead, 
+simply place script at the end of the file (after any custom elements).
+
+## Polymer element APIs
+
+To use Polymer elements effectively, it's important to be familiar with a
+few of the common Polymer element APIs.
+
+### Attribute and properties
+
+The Polymer element docs list element _properties_, but not element attributes. Unless otherwise
+noted, every property on a Polymer element has a corresponding _attribute_. Use the attribute name
+when configuring a property from markup, or when creating a Polymer data binding to a property.
+
+When mapping attribute names to property names:
+
+*   Attribute names are converted to lowercase property names. For example,
+    the _attribute_ `firstName` maps to the property `firstname`.
+
+*   Attribute names with _dashes_ are converted to _camelCase_ property names 
+    by capitalizing the character following each dash, then removing the dashes. 
+    For example, the _attribute_ `first-name` maps to the property `firstName`.
+
+####  Passing object and array values in attributes
+
+[HTML attributes](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes) are string values, but sometimes you need to pass more complicated values into a custom element, such as objects or arrays. Ultimately, it's up to the element author to decide how to decode values passed in as attributes, but many Polymer elements understand attribute values that are a JSON-serialized object or array. For example:
+
+    <roster-list persons='[{"name": "John"}, {"name": "Bob"}]'></roster-list>
+
+For Polymer elements, you can find the expected type for each attribute listed in the API docs. If you pass the wrong type, it may be decoded incorrectly.
+
+The same mappings happen in reverse when converting property names to attribute
+names (for example, if a property is defined using `reflectToAttribute: true`.)
+
+#### Data binding
+
+Polymer elements also support data binding, using a format like this:
+
+    <my-element property-name="{{hostProperty}}"></my-element>
+
+These data binding annotations are only supported in two places:
+
+- In the [local DOM template](https://www.polymer-project.org/1.0/docs/devguide/local-dom.html#template-stamping) of a Polymer element.
+
+- Inside an [autobinding template](https://www.polymer-project.org/1.0/docs/devguide/templates.html#dom-bind).
+
+For more information see [Data binding](https://www.polymer-project.org/1.0/docs/devguide/data-binding.html).
+
+### DOM manipulation
+
+Because not all browsers support shadow DOM natively, Polymer uses a shim called shady DOM
+to achieve shadow DOM's goals of composition and style encapsulation. 
+
+As a result, if you are manipulating a Polymer element, you need to use the `Polymer.dom` 
+APIs to maintain the correct DOM structure. This is particularly important when adding or removing
+children from a Polymer element, for example.
+
+For more information, see [DOM API](https://www.polymer-project.org/1.0/docs/devguide/local-dom.html#dom-api).
+
+### Custom CSS properties and mixins
+
+Many of the Polymer elements can be styled using custom CSS properties and mixins. 
+
+Property and mixin values can be specified:
+
+- Inside a Polymer element's `<style>` tag to specify values scoped to that element.
+- Inside a `custom-style` element to specify values in the document scope.
+
+For more information, see [Cross-scope styling](https://www.polymer-project.org/1.0/docs/devguide/styling.html#xscope-styling)
+and [Custom element for document styling (custom-style)](https://www.polymer-project.org/1.0/docs/devguide/styling.html#custom-style).
+
+<!-- 
+## Next steps
+
+Now that you've got the basic idea of using and installing elements, it's time to start
+building something!
+
+In the next section we'll cover using the Core layout elements
+to structure an application's layout.  Continue on to:

+<a name="basic"></a>
+## A basic animatable element
+
+Elements that can be animated should implement the `Polymer.NeonAnimatableBehavior` behavior, or `Polymer.NeonAnimationRunnerBehavior` if they're also responsible for running an animation.
+
+```js
+Polymer({
+  is: 'my-animatable',
+  behaviors: [
+    Polymer.NeonAnimationRunnerBehavior
+  ],
+  properties: {
+    animationConfig: {
+      value: function() {
+        return {
+          // provided by neon-animation/animations/scale-down-animation.html
+          name: 'scale-down-animation',
+          node: this
+        }
+      }
+    }
+  },
+  listeners: {
+    // this event is fired when the animation finishes
+    'neon-animation-finish': '_onNeonAnimationFinish'
+  },
+  animate: function() {
+    // run scale-down-animation
+    this.playAnimation();
+  },
+  _onNeonAnimationFinish: function() {
+    console.log('animation done!');
+  }
+});
+```
+
+[Live demo](http://morethanreal.github.io/neon-animation-demo/bower_components/neon-animation/demo/doc/basic.html)
+
+<a name="configuration"></a>
+## Animation configuration
+
+<a name="configuration-types"></a>
+### Animation types
+
+An element might run different animations, for example it might do something different when it enters the view and when it exits from view. You can set the `animationConfig` property to a map from an animation type to configuration.
+
+```js
+Polymer({
+  is: 'my-dialog',
+  behaviors: [
+    Polymer.NeonAnimationRunnerBehavior
+  ],
+  properties: {
+    opened: {
+      type: Boolean
+    },
+    animationConfig: {
+      value: function() {
+        return {
+          'entry': {
+            // provided by neon-animation/animations/scale-up-animation.html
+            name: 'scale-up-animation',
+            node: this
+          },
+          'exit': {
+            // provided by neon-animation-animations/fade-out-animation.html
+            name: 'fade-out-animation',
+            node: this
+          }
+        }
+      }
+    }
+  },
+  listeners: {
+    'neon-animation-finish': '_onNeonAnimationFinish'
+  },
+  show: function() {
+    this.opened = true;
+    this.style.display = 'inline-block';
+    // run scale-up-animation
+    this.playAnimation('entry');
+  },
+  hide: function() {
+    this.opened = false;
+    // run fade-out-animation
+    this.playAnimation('fade-out-animation');
+  },
+  _onNeonAnimationFinish: function() {
+    if (!this.opened) {
+      this.style.display = 'none';
+    }
+  }
+});
+```
+
+[Live demo](http://morethanreal.github.io/neon-animation-demo/bower_components/neon-animation/demo/doc/types.html)
+
+You can also use the convenience properties `entryAnimation` and `exitAnimation` to set `entry` and `exit` animations:
+
+```js
+properties: {
+  entryAnimation: {
+    value: 'scale-up-animation'
+  },
+  exitAnimation: {
+    value: 'fade-out-animation'
+  }
+}
+```
+
+<a name="configuration-properties"></a>
+### Configuration properties
+
+You can pass additional parameters to configure an animation in the animation configuration object.
+All animations should accept the following properties:
+
+ * `name`: The name of an animation, ie. an element implementing `Polymer.NeonAnimationBehavior`.
+ * `node`: The target node to apply the animation to. Defaults to `this`.
+ * `timing`: Timing properties to use in this animation. They match the [Web Animations Animation Effect Timing interface](https://w3c.github.io/web-animations/#the-animationeffecttiming-interface). The
+ properties include the following:
+     * `duration`: The duration of the animation in milliseconds.
+     * `delay`: The delay before the start of the animation in milliseconds.
+     * `easing`: A timing function for the animation. Matches the CSS timing function values.
+
+Animations may define additional configuration properties and they are listed in their documentation.
+
+<a name="configuration-multiple"></a>
+### Using multiple animations
+
+Set the animation configuration to an array to combine animations, like this:
+
+```js
+animationConfig: {
+  value: function() {
+    return {
+      // fade-in-animation is run with a 50ms delay from slide-down-animation
+      'entry': [{
+        name: 'slide-down-animation',
+        node: this
+      }, {
+        name: 'fade-in-animation',
+        node: this,
+        timing: {delay: 50}
+      }]
+    }
+  }
+}
+```
+
+<a name="configuration-encapsulation"></a>
+### Running animations encapsulated in children nodes
+
+You can include animations in the configuration that are encapsulated in a child element that implement `Polymer.NeonAnimatableBehavior` with the `animatable` property.
+
+```js
+animationConfig: {
+  value: function() {
+    return {
+      // run fade-in-animation on this, and the entry animation on this.$.myAnimatable
+      'entry': [
+        {name: 'fade-in-animation', node: this},
+        {animatable: this.$.myAnimatable, type: 'entry'}
+      ]
+    }
+  }
+}
+```
+
+<a name="page-transitions"></a>
+## Page transitions
+
+*The artist formerly known as `<core-animated-pages>`*
+
+The `neon-animated-pages` element manages a set of pages to switch between, and runs animations between the page transitions. It implements the `Polymer.IronSelectableBehavior` behavior. Each child node should implement `Polymer.NeonAnimatableBehavior` and define the `entry` and `exit` animations. During a page transition, the `entry` animation is run on the new page and the `exit` animation is run on the old page.
+
+<a name="shared-element"></a>
+### Shared element animations
+
+Shared element animations work on multiple nodes. For example, a "hero" animation is used during a page transition to make two elements from separate pages appear to animate as a single element. Shared element animation configurations have an `id` property that identify they belong in the same animation. Elements containing shared elements also have a `sharedElements` property defines a map from `id` to element, the element involved with the animation.
+
+In the incoming page:
+
+```js
+properties: {
+  animationConfig: {
+    value: function() {
+      return {
+        // the incoming page defines the 'entry' animation
+        'entry': {
+          name: 'hero-animation',
+          id: 'hero',
+          toPage: this
+        }
+      }
+    }
+  },
+  sharedElements: {
+    value: function() {
+      return {
+        'hero': this.$.hero
+      }
+    }
+  }
+}
+```
+
+In the outgoing page:
+
+```js
+properties: {
+  animationConfig: {
+    value: function() {
+      return {
+        // the outgoing page defines the 'exit' animation
+        'exit': {
+          name: 'hero-animation',
+          id: 'hero',
+          fromPage: this
+        }
+      }
+    }
+  },
+  sharedElements: {
+    value: function() {
+      return {
+        'hero': this.$.otherHero
+      }
+    }
+  }
+}
+```
+
+<a name="declarative-page"></a>
+### Declarative page transitions
+
+For convenience, if you define the `entry-animation` and `exit-animation` attributes on `<neon-animated-pages>`, those animations will apply for all page transitions.
+
+For example:
+
+```js
+<neon-animated-pages id="pages" class="flex" selected="[[selected]]" entry-animation="slide-from-right-animation" exit-animation="slide-left-animation">
+  <neon-animatable>1</neon-animatable>
+  <neon-animatable>2</neon-animatable>
+  <neon-animatable>3</neon-animatable>
+  <neon-animatable>4</neon-animatable>
+  <neon-animatable>5</neon-animatable>
+</neon-animated-pages>
+```
+
+The new page will slide in from the right, and the old page slide away to the left.
+
+<a name="animations"></a>
+## Included animations
+
+Single element animations:
+
+ * `fade-in-animation` Animates opacity from `0` to `1`.
+ * `fade-out-animation` Animates opacity from `1` to `0`.
+ * `scale-down-animation` Animates transform from `scale(1)` to `scale(0)`.
+ * `scale-up-animation` Animates transform from `scale(0)` to `scale(1)`.
+ * `slide-down-animation` Animates transform from `translateY(-100%)` to `none`.
+ * `slide-up-animation` Animates transform from `none` to `translateY(-100%)`.
+ * `slide-left-animation` Animates transform from `none` to `translateX(-100%)`;
+ * `slide-right-animation` Animates transform from `none` to `translateX(100%)`;
+ * `slide-from-left-animation` Animates transform from `translateX(-100%)` to `none`;
+ * `slide-from-right-animation` Animates transform from `translateX(100%)` to `none`;
+
+ * `transform-animation` Animates a custom transform.
+
+Note that there is a restriction that only one transform animation can be applied on the same element at a time. Use the custom `transform-animation` to combine transform properties.
+
+Shared element animations
+
+ * `hero-animation` Animates an element such that it looks like it scales and transforms from another element.
+ * `ripple-animation` Animates an element to full screen such that it looks like it ripples from another element.
+
+Group animations
+ * `cascaded-animation` Applys an animation to an array of elements with a delay between each.
+
+<a name="demos"></a>
