+`cascade-transition` slides the children of a container up in sequence, creating a
+reverse waterfall effect. It works well with both grids and lists. Configure the
+duration of the transition with the global variable `CoreStyle.g.transitions.cascadeDuration`.
+
+Example:
+
+    <core-animated-pages transition="cascade-transition">
+      <section>
+        <div id="container" cascade>
+          <div>item 1</div>
+          <div>item 2</div>
+          <div>item 3</div>
+          <div>item 4</div>
+          <div>item 5</div>
+          <div>item 6</div>
+          <div>item 7</div>
+        </div>
+      </section>
+      <section></section>
+    </core-animated-pages>
+
+In the above example, the immediate children of `#container` will slide up in
+sequence when the page transitions from 0 to 1.
+
+The items can optionally fade in as they slide. Add the `fade` attribute to
+the container to do that and configure the duration of the opacity transition with
+the global variable `CoreStyle.g.transitions.cascadeFadeDuration`.
