| 16 `<hero-animation>` is a shared element animation that scales and transform an el
ement such that it | |
| 17 appears to be shared between two pages. Use this in `<neon-animated-pages>`. The
source page | |
| 18 should use this animation in an 'exit' animation and set the `fromPage` configur
ation property to | |
| 19 itself, and the destination page should use this animation in an `entry` animati
on and set the | |
| 20 `toPage` configuration property to itself. They should also define the hero elem
ents in the | |
| 21 `sharedElements` property (not a configuration property, see | |
| 22 `Polymer.NeonSharedElementAnimatableBehavior`). | |
| 23 | |
| 24 Configuration: | |
