+Material design: [Icon toggles](https://www.google.com/design/spec/components/buttons.html#buttons-toggle-buttons) |
+ |
+`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 the `--paper-icon-button-ink-color` custom property. |
+ |
+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 | `--disabled-text-color` |
+`--paper-icon-button-ink-color` | Selected/focus ripple color | `--primary-text-color` |
+`--paper-icon-button` | Mixin for a button | `{}` |
+`--paper-icon-button-disabled` | Mixin for a disabled button | `{}` |
+`--paper-icon-button-hover` | Mixin for button on hover | `{}` |
