| 13 Material Design: <a href="https://spec.googleplex.com/quantum/components/buttons
.html">Buttons</a> | |
| 14 | |
| 15 `paper-icon-button` is a button with an image placed at the center. When the use
r touches | |
| 16 the button, a ripple effect emanates from the center of the button. | |
| 17 | |
| 18 You may import `core-icons` to use with this element, or provide an URL to a cus
tom icon. | |
| 19 See `core-iconset` for more information about how to use a custom icon set. | |
| 20 | |
| 21 Example: | |
| 22 | |
| 23 <link href="path/to/core-icons/core-icons.html" rel="import"> | |
| 24 | |
| 25 <paper-icon-button icon="favorite"></paper-icon-button> | |
| 26 <paper-icon-button src="star.png"></paper-icon-button> | |
| 27 | |
| 28 Styling | |
| 29 ------- | |
| 30 | |
| 31 Style the button with CSS as you would a normal DOM element. If you are using th
e icons | |
| 32 provided by `core-icons`, they will inherit the foreground color of the button. | |
| 33 | |
| 34 /* make a red "favorite" button */ | |
| 35 <paper-icon-button icon="favorite" style="color: red;"></paper-icon-button> | |
| 36 | |
| 37 By default, the ripple is the same color as the foreground at 25% opacity. You m
ay | |
| 38 customize the color using this selector: | |
| 39 | |
| 40 /* make #my-button use a blue ripple instead of foreground color */ | |
| 41 #my-button::shadow #ripple { | |
| 42 color: blue; | |
| 43 } | |
| 44 | |
| 45 The opacity of the ripple is not customizable via CSS. | |
| 46 | |
| 47 Accessibility | |
| 48 ------------- | |
| 49 | |
| 50 The button is accessible by default if you use the `icon` property. By default,
the | |
| 51 `aria-label` attribute will be set to the `icon` property. If you use a custom i
con, | |
| 52 you should ensure that the `aria-label` attribute is set. | |
| 53 | |
| 54 <paper-icon-button src="star.png" aria-label="star"></paper-icon-button> | |
| 55 | |
| 56 @element paper-icon-button | |
| 57 @extends paper-button-base | |
