| 13 Material Design: <a href="http://www.google.com/design/spec/components/buttons.h
tml">Button</a> | |
| 14 | |
| 15 `paper-fab` is a floating action button. It contains an image placed in the cent
er and | |
| 16 comes in two sizes: regular size and a smaller size by applying the attribute `m
ini`. When | |
| 17 the user touches the button, a ripple effect emanates from the center of the but
ton. | |
| 18 | |
| 19 You may import `core-icons` to use with this element, or provide an URL to a cus
tom icon. | |
| 20 See `core-iconset` for more information about how to use a custom icon set. | |
| 21 | |
| 22 Example: | |
| 23 | |
| 24 <link href="path/to/core-icons/core-icons.html" rel="import"> | |
| 25 | |
| 26 <paper-fab icon="add"></paper-fab> | |
| 27 <paper-fab mini icon="favorite"></paper-fab> | |
| 28 <paper-fab src="star.png"></paper-fab> | |
| 29 | |
| 30 Styling | |
| 31 ------- | |
| 32 | |
| 33 Style the button with CSS as you would a normal DOM element. If you are using th
e icons | |
| 34 provided by `core-icons`, the icon will inherit the foreground color of the butt
on. | |
| 35 | |
| 36 /* make a blue "cloud" button */ | |
| 37 <paper-fab icon="cloud" style="color: blue;"></paper-fab> | |
| 38 | |
| 39 By default, the ripple is the same color as the foreground at 25% opacity. You m
ay | |
| 40 customize the color using this selector: | |
| 41 | |
| 42 /* make #my-button use a blue ripple instead of foreground color */ | |
| 43 #my-button::shadow #ripple { | |
| 44 color: blue; | |
| 45 } | |
| 46 | |
| 47 The opacity of the ripple is not customizable via CSS. | |
| 48 | |
| 49 Accessibility | |
| 50 ------------- | |
| 51 | |
| 52 The button is accessible by default if you use the `icon` property. By default,
the | |
| 53 `aria-label` attribute will be set to the `icon` property. If you use a custom i
con, | |
| 54 you should ensure that the `aria-label` attribute is set. | |
| 55 | |
| 56 <paper-fab src="star.png" aria-label="star"></paper-fab> | |
