 103 `cascade-transition` slides the children of a container up in sequence, creating a
 104 reverse waterfall effect. It works well with both grids and lists. Configure the
 105 duration of the transition with the global variable `CoreStyle.g.transitions.cascadeDuration`.
 106
 107 Example:
 108
 109     <core-animated-pages transition="cascade-transition">
 110       <section>
 111         <div id="container" cascade>
 112           <div>item 1</div>
 113           <div>item 2</div>
 114           <div>item 3</div>
 115           <div>item 4</div>
 116           <div>item 5</div>
 117           <div>item 6</div>
 118           <div>item 7</div>
 119         </div>
 120       </section>
 121       <section></section>
 122     </core-animated-pages>
 123
 124 In the above example, the immediate children of `#container` will slide up in
 125 sequence when the page transitions from 0 to 1.
 126
 127 The items can optionally fade in as they slide. Add the `fade` attribute to
 128 the container to do that and configure the duration of the opacity transition with
 129 the global variable `CoreStyle.g.transitions.cascadeFadeDuration`.
