<h1>Exploring the Dom Collection's API</h1>

<div class="exampleIntro">
  <p>In this example, the use of several key Dom Collection methods is explored.  Given the markup in the source section, you can invoke any of the methods by clicking on them; the Source is updated, as is its in-browser appearance (Render).  In the Outupt section, you can review the elements that are selected or affected (or, in a few cases, the JavaScript <code>return</code> value) of the function you invoked.</p>
