| 16 `<ripple-animation>` scales and transform an element such that it appears to rip
ple from either |
| 17 a shared element, or from a screen position, to full screen. |
| 18 |
| 19 If using as a shared element animation in `<neon-animated-pages>`, use this anim
ation in an `exit` |
| 20 animation in the source page and in an `entry` animation in the destination page
. Also, define the |
| 21 hero elements in the `sharedElements` property (not a configuration property, se
e |
| 22 `Polymer.NeonSharedElementAnimatableBehavior`). |
| 23 |
| 24 If using a screen position, define the `gesture` property. |
| 25 |
| 26 Configuration: |
| 27 ``` |
| 28 { |
| 29 name: 'ripple-animation`. |
| 30 id: <shared-element-id>, /* set this or gesture */ |
| 31 gesture: {x: <page-x>, y: <page-y>}, /* set this or id */ |
| 32 timing: <animation-timing>, |
| 33 toPage: <node>, /* define for the destination page */ |
| 34 fromPage: <node>, /* define for the source page */ |
