tml">Buttons</a> | |
| 19 | |
| 20 `paper-button` is a button. When the user touches the button, a ripple effect em
anates | |
| 21 from the point of contact. It may be flat or raised. A raised button is styled w
ith a | |
| 22 shadow. | |
| 23 | |
| 24 Example: | |
| 25 | |
| 26 <paper-button>flat button</paper-button> | |
| 27 <paper-button raised>raised button</paper-button> | |
| 28 <paper-button noink>No ripple effect</paper-button> | |
| 29 <paper-button toggles>toggle-able button</paper-button> | |
| 30 | |
| 31 A button that has `toggles` true will remain `active` after being clicked (and | |
| 32 will have an `active` attribute set). For more information, see the `Polymer.Iro
nButtonState` | |
| 33 behavior. | |
| 34 | |
| 35 You may use custom DOM in the button body to create a variety of buttons. For ex
ample, to | |
| 36 create a button with an icon and some text: | |
| 37 | |
| 38 <paper-button> | |
| 39 <iron-icon icon="favorite"></iron-icon> | |
| 40 custom button content | |
| 41 </paper-button> | |
| 42 | |
| 43 ### Styling | |
| 44 | |
| 45 Style the button with CSS as you would a normal DOM element. | |
| 46 | |
| 47 /* make #my-button green with yellow text */ | |
| 48 #my-button { | |
| 49 background: green; | |
| 50 color: yellow; | |
| 51 } | |
| 52 | |
| 53 By default, the ripple is the same color as the foreground at 25% opacity. You m
ay | |
| 54 customize the color using this selector: | |
| 55 | |
| 56 /* make #my-button use a blue ripple instead of foreground color */ | |
| 57 #my-button::shadow paper-ripple { | |
| 58 color: blue; | |
| 59 } | |
| 60 | |
| 61 The opacity of the ripple is not customizable via CSS. | |
| 62 | |
| 63 The following custom properties and mixins are also available for styling: | |
| 64 | |
| 65 Custom property | Description | Default | |
| 66 ----------------|-------------|---------- | |
| 67 `--paper-button-flat-focus-color` | Background color of a focused flat button |
`--paper-grey-200` | |
| 68 `--paper-button` | Mixin applied to the button | `{}` | |
| 69 `--paper-button-disabled` | Mixin applied to the disabled button | `{}` | |
