| 22 |
| 23 `paper-fab` is a floating action button. It contains an image placed in the cent
er and |
| 24 comes in two sizes: regular size and a smaller size by applying the attribute `m
ini`. When |
| 25 the user touches the button, a ripple effect emanates from the center of the but
ton. |
| 26 |
| 27 You may import `iron-icons` to use with this element, or provide a URL to a cust
om icon. |
| 28 See `iron-iconset` for more information about how to use a custom icon set. |
| 29 |
| 30 Example: |
| 31 |
| 32 <link href="path/to/iron-icons/iron-icons.html" rel="import"> |
| 33 |
| 34 <paper-fab icon="add"></paper-fab> |
| 35 <paper-fab mini icon="favorite"></paper-fab> |
| 36 <paper-fab src="star.png"></paper-fab> |
