| 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> |
| |
| To use `paper-icon-button` as a link, wrap it in an anchor tag. Since `paper-icon-button` |
| will already receive focus, you may want to prevent the anchor tag from receiving focus |
| as well by setting its tabindex to -1. |
| |
| <a href="https://www.polymer-project.org" tabindex="-1"> |
| <paper-icon-button icon="polymer"></paper-icon-button> |
| </a> |
| |
| ### 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 | `{}` |
