| 12 `<core-transition>` is an abstraction of an animation. It is used to implement p
luggable | |
| 13 transitions, for example in `<core-overlay>`. You can extend this class to creat
e a custom | |
| 14 animation, instantiate it, and import it where you need the animation. | |
| 15 | |
| 16 All instances of `<core-transition>` are stored in a single database with `type=
transition`. | |
| 17 For more about the database, please see the documentation for `<core-meta>`. | |
| 18 | |
| 19 Each instance of `<core-transition>` objects are shared across all the clients,
so you should | |
| 20 not store state information specific to the animated element in the transition.
Rather, store | |
| 21 it on the element. | |
| 22 | |
| 23 Example: | |
| 24 | |
| 25 my-transition.html: | |
| 26 | |
| 27 <polymer-element name="my-transition" extends="core-transition"> | |
| 28 <script> | |
| 29 go: function(node) { | |
| 30 node.style.transition = 'opacity 1s ease-out'; | |
| 31 node.style.opacity = 0; | |
| 32 } | |
| 33 </script> | |
| 34 </polymer-element> | |
| 35 | |
| 36 <my-transition id="my-fade-out"></my-transition> | |
