When the user touches the button, a ripple effect emanates from the point of contact. It may be flat or raised. A raised button is styled with a shadow. Example: <paper-button>Flat button</paper-button> <paper-button raised>Raised button</paper-button> <paper-button noink>No ripple effect</paper-button> <paper-button toggles>Toggle-able button</paper-button> A button that has `toggles` true will remain `active` after being clicked (and will have an `active` attribute set). For more information, see the `Polymer.IronButtonState` behavior. You may use custom DOM in the button body to create a variety of buttons. For example, to create a button with an icon and some text: <paper-button> <iron-icon icon="favorite"></iron-icon> custom button content </paper-button> ### Styling Style the button with CSS as you would a normal DOM element. paper-button.fancy { background: green; color: yellow; } paper-button.fancy:hover { background: lime; } paper-button[disabled], paper-button[toggles][active] { background: red; } By default, the ripple is the same color as the foreground at 25% opacity. You may customize the color using the `--paper-button-ink-color` custom property. The following custom properties and mixins are also available for styling: Custom property | Description | Default ----------------|-------------|---------- `--paper-button-ink-color` | Background color of the ripple | `Based on the button's color` `--paper-button` | Mixin applied to the button | `{}` `--paper-button-disabled` | Mixin applied to the disabled button. Note that you can also use the `paper-button[disabled]` selector | `{}` `--paper-button-flat-keyboard-focus` | Mixin applied to a flat button after it's been focused using the keyboard | `{}` `--paper-button-raised-keyboard-focus` | Mixin applied to a raised button after it's been focused using the keyboard | `{}` @demo demo/index.html --> <dom-module id="paper-button"> <template strip-whitespace> <style include="paper-material"> :host { display: inline-block; position: relative; box-sizing: border-box; min-width: 5.14em; margin: 0 0.29em; background: transparent; text-align: center; font: inherit; text-transform: uppercase; outline-width: 0; border-radius: 3px; -moz-user-select: none; -ms-user-select: none; -webkit-user-select: none; user-select: none; cursor: pointer; z-index: 0; padding: 0.7em 0.57em; @apply(--paper-button); } :host([raised].keyboard-focus) { font-weight: bold; @apply(--paper-button-raised-keyboard-focus); } :host(:not([raised]).keyboard-focus) { font-weight: bold; @apply(--paper-button-flat-keyboard-focus); } :host([disabled]) { background: #eaeaea; color: #a8a8a8; cursor: auto; pointer-events: none; @apply(--paper-button-disabled); } paper-ripple { color: var(--paper-button-ink-color); } :host > ::content * { text-transform: inherit; } </style> <content></content> </template> </dom-module> <script> Polymer({ is: 'paper-button', behaviors: [ Polymer.PaperButtonBehavior ], properties: { /** * If true, the button should be styled with a shadow. */ raised: { type: Boolean, reflectToAttribute: true, value: false, observer: '_calculateElevation' } }, _calculateElevation: function() { if (!this.raised) { this.elevation = 0; } else { Polymer.PaperButtonBehaviorImpl._calculateElevation.apply(this); } } }); </script>
