Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Buttons</a>
`paper-icon-button` is a button with an image placed at the center. When the user touches
the button, a ripple effect emanates from the center of the button.
`paper-icon-button` includes a default icon set. Use `icon` to specify which icon
from the icon set to use.
<paper-icon-button icon="menu"></paper-icon-button>
See [`iron-iconset`](#iron-iconset) for more information about
how to use a custom icon set.
Example:
<link href="path/to/iron-icons/iron-icons.html" rel="import">
<paper-icon-button icon="favorite"></paper-icon-button>
<paper-icon-button src="star.png"></paper-icon-button>
###Styling
Style the button with CSS as you would a normal DOM element. If you are using the icons
provided by `iron-icons`, they will inherit the foreground color of the button.
/* make a red "favorite" button */
<paper-icon-button icon="favorite" style="color: red;"></paper-icon-button>
By default, the ripple is the same color as the foreground at 25% opacity. You may
customize the color using this selector:
/* make #my-button use a blue ripple instead of foreground color */
#my-button::shadow #ripple {
color: blue;
}
The opacity of the ripple is not customizable via CSS.
The following custom properties and mixins are available for styling:
Custom property | Description | Default
----------------|-------------|----------
`--paper-icon-button-disabled-text` | The color of the disabled button | `--primary-text-color`
`--paper-icon-button-ink-color` | Selected/focus ripple color | `--default-primary-color`
`--paper-icon-button` | Mixin for a button | `{}`
`--paper-icon-button-disabled` | Mixin for a disabled button | `{}`
