-<p><span>他的属性最初是在{{domxref("element遍历")}}纯接口中定义的。由于这个接口包含两组不同的属性,一个针对具有子元素的{{domxref("Node")}},一个针对子元素的属性,因此它们被移动到两个单独的纯接口中,{{domxref("ParentNode")}}和{{domxref("ChildNode")}}。在本例中,firstElementChild移动到{{domxref("ParentNode")}}。这是一个相当技术性的更改,不应该影响兼容性。</span></p>

-<div class="note">
-<p>This property was initially defined in the {{domxref("ElementTraversal")}} pure interface. As this interface contained two distinct set of properties, one aimed at {{domxref("Node")}} that have children, one at those that are children, they have been moved into two separate pure interfaces, {{domxref("ParentNode")}} and {{domxref("ChildNode")}}. In this case, <code>lastElementChild</code> moved to {{domxref("ParentNode")}}. This is a fairly technical change that shouldn't affect compatibility.</p>
