-`hero-transition` transforms two elements in different pages such that they appear
-to be shared across the pages.
-
-Example:
-
-    <core-animated-pages transition="hero-transition">
-      <section layout horizontal>
-        <div id="div1" flex></div>
-        <div id="div2" flex hero-id="shared" hero></div>
-      </section>
-      <section>
-      <section layout horizontal>
-        <div id="div3" flex hero-id="shared" hero></div>
-        <div id="div4" flex></div>
-      </section>
-      </section>
-    </core-animated-pages>
-
-In the above example, the elements `#div2` and `#div3` shares the same `hero-id`
-attribute and a single element appears to translate and scale smoothly between
-the two positions during a page transition.
-
-Both elements from the source and destination pages must share the same `hero-id`
-and must both contain the `hero` attribute to trigger the transition. The separate
-`hero` attribute allows you to use binding to configure the transition:
-
-Example:
-
-    <core-animated-pages transition="hero-transition">
-      <section layout horizontal>
-        <div id="div1" flex hero-id="shared" hero?="{{selected == 0}}"></div>
-        <div id="div2" flex hero-id="shared" hero?="{{selected == 1}}"></div>
-      </section>
-      <section>
-      <section layout horizontal>
-        <div id="div3" flex hero-id="shared" hero></div>
-      </section>
-      </section>
-    </core-animated-pages>
-
-In the above example, either `#div1` or `#div2` scales to `#div3` during a page transition,
-depending on the value of `selected`.
-
-Because it is common to share elements with different `border-radius` values, by default
-this transition will also animate the `border-radius` property.
-
-You can configure the duration of the hero transition with the global variable
-`CoreStyle.g.transitions.heroDuration`.
