`slide-down` slides an element in the outgoing page from the top of the window and
slides in an element in the incoming page from the top of the window during a page
transition. You can configure the duration of the transition with the global variable
`CoreStyle.g.transitions.slideDuration`.

Example:

    <core-animated-pages transition="slide-down">
      <section>
        <div id="div1" slide-down></div>
      </section>
      <section></section>
    </core-animated-pages>
