Revision 509201 of ParentNode

<p>{{DomRef}}</p>
<p>The <code><strong>ParentNode</strong></code> interface contains methods that are particular to {{domxref("Node")}} objects that can have children.</p>
<p><code>ParentNode</code> is a raw interface and no object of this type can be created; it is implemented by {{domxref("Element")}}, {{domxref("Document")}}, and {{domxref("DocumentFragment")}} objects.</p>
<p>&nbsp;</p>

  {{ domxref("ParentNode.children") }} {{experimental_inline}} {{readonlyInline}}</dt>
 <dd>
  Returns a live {{domxref("HTMLCollection")}} containing all objects of type {{domxref("Element")}} that are children of this <code>ParentNode</code>.</dd>

  {{ domxref("ParentNode.firstElementChild") }} {{experimental_inline}} {{readonlyInline}}</dt>
 <dd>
  Returns the {{domxref("Element")}} that is the first child of this <code>ParentNode</code>, or <code>null</code> if there is none.</dd>
 <dt>
  {{ domxref("ParentNode.lastElementChild") }} {{experimental_inline}} {{readonlyInline}}</dt>
 <dd>
  Returns the {{domxref("Element")}} that is the last child of this <code>ParentNode</code>, or <code>null</code> if there is none.</dd>

    The {{domxref("Document")}} and {{domxref("DocumentFragment")}} implemented the new interfaces.<br />
