| 13 | |
| 14 `core-animation` is a convenience element to use web animations with Polymer ele
ments. It | |
| 15 allows you to create a web animation declaratively. You can extend this class to
create | |
| 16 new types of animations and combine them with `core-animation-group`. | |
| 17 | |
| 18 Example to create animation to fade out an element over 500ms: | |
| 19 | |
| 20 <core-animation id="fadeout" duration="500"> | |
| 21 <core-animation-keyframe> | |
| 22 <core-animation-prop name="opacity" value="1"></core-animation-prop> | |
| 23 </core-animation-keyframe> | |
| 24 <core-animation-keyframe> | |
| 25 <core-animation-prop name="opacity" value="0"></core-animation-prop> | |
| 26 </core-animation-keyframe> | |
| 27 </core-animation> | |
| 28 | |
| 29 <div id="el">Fade me out</div> | |
| 30 | |
| 31 <script> | |
| 32 var animation = document.getElementById('fadeout'); | |
| 33 animation.target = document.getElementById('el'); | |
| 34 animation.play(); | |
| 35 </script> | |
| 36 | |
| 37 Or do the same imperatively: | |
| 38 | |
| 39 var animation = new CoreAnimation(); | |
| 40 animation.duration = 500; | |
| 41 animation.keyframes = [ | |
| 42 {opacity: 1}, | |
| 43 {opacity: 0} | |
| 44 ]; | |
| 45 animation.target = document.getElementById('el'); | |
| 46 animation.play(); | |
| 47 | |
| 48 You can also provide a javascript function instead of keyframes to the animation
. This | |
| 49 behaves essentially the same as `requestAnimationFrame`: | |
| 50 | |
| 51 var animation = new CoreAnimation(); | |
| 52 animation.customEffect = function(timeFraction, target, animation) { | |
| 53 // do something custom | |
| 54 }; | |
| 55 animation.play(); | |
| 56 | |
| 57 Elements that are targets to a `core-animation` are given the `core-animation-ta
rget` class. | |

| 68 `core-animation-keyframe` represents a keyframe in a `core-animation`. Use them
as children of | |
| 69 `core-animation` elements to create web animations declaratively. If the `offset
` property is | |
| 70 unset, the keyframes will be distributed evenly within the animation duration. U
se | |
| 71 `core-animation-prop` elements as children of this element to specify the CSS pr
operties for | |
| 72 the animation. | |
