| 20 Material design: [Surface reaction](https://www.google.com/design/spec/animation
/responsive-interaction.html#responsive-interaction-surface-reaction) | |
| 21 | |
| 22 `paper-ripple` provides a visual effect that other paper elements can | |
| 23 use to simulate a rippling effect emanating from the point of contact. The | |
| 24 effect can be visualized as a concentric circle with motion. | |
| 25 | |
| 26 Example: | |
| 27 | |
| 28 <div style="position:relative"> | |
| 29 <paper-ripple></paper-ripple> | |
| 30 </div> | |
| 31 | |
| 32 Note, it's important that the parent container of the ripple be relative positio
n, otherwise | |
| 33 the ripple will emanate outside of the desired container. | |
| 34 | |
| 35 `paper-ripple` listens to "mousedown" and "mouseup" events so it would display r
ipple | |
| 36 effect when touches on it. You can also defeat the default behavior and | |
| 37 manually route the down and up actions to the ripple element. Note that it is | |
| 38 important if you call `downAction()` you will have to make sure to call | |
| 39 `upAction()` so that `paper-ripple` would end the animation loop. | |
| 40 | |
| 41 Example: | |
| 42 | |
| 43 <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple> | |
| 44 ... | |
| 45 downAction: function(e) { | |
| 46 this.$.ripple.downAction({x: e.x, y: e.y}); | |
| 47 }, | |
| 48 upAction: function(e) { | |
| 49 this.$.ripple.upAction(); | |
| 50 } | |
| 51 | |
| 52 Styling ripple effect: | |
| 53 | |
| 54 Use CSS color property to style the ripple: | |
| 55 | |
| 56 paper-ripple { | |
| 57 color: #4285f4; | |
| 58 } | |
| 59 | |
| 60 Note that CSS color property is inherited so it is not required to set it on | |
| 61 the `paper-ripple` element directly. | |
| 62 | |
| 63 By default, the ripple is centered on the point of contact. Apply the `recenter
s` | |
| 64 attribute to have the ripple grow toward the center of its container. | |
| 65 | |
| 66 <paper-ripple recenters></paper-ripple> | |
| 67 | |
| 68 You can also center the ripple inside its container from the start. | |
| 69 | |
| 70 <paper-ripple center></paper-ripple> | |
| 71 | |
| 72 Apply `circle` class to make the rippling effect within a circle. | |
| 73 | |
| 74 <paper-ripple class="circle"></paper-ripple> | |
