`<slide-down-animation>` animates the transform of an element from `translateY(-100%)` to `none`.
The `transformOrigin` defaults to `50% 0`.
Configuration:
```
{
name: 'slide-down-animation',
node: <node>,
transformOrigin: <transform-origin>,
timing: <animation-timing>
}
```
-->
<script>
Polymer({
is: 'slide-down-animation',
behaviors: [
Polymer.NeonAnimationBehavior
],
configure: function(config) {
var node = config.node;
if (config.transformOrigin) {
this.setPrefixedProperty(node, 'transformOrigin', config.transformOrigin);
} else {
this.setPrefixedProperty(node, 'transformOrigin', '50% 0');
}
this._effect = new KeyframeEffect(node, [
{'transform': 'translateY(-100%)'},
{'transform': 'none'}
], this.timingFromConfig(config));
return this._effect;
}
});
