<p>As a CSS selector, the child combinator is supported by all modern web browsers including Safari, Firefox, Opera, Chrome, and Internet Explorer 7 and above, but notably not by Internet Explorer versions 6 and below. However, in jQuery, this selector (along with all others) works across all supported browsers, including IE6.</p>
<p>The child combinator (E <strong>&gt;</strong> F) can be thought of as a more specific form of the descendant combinator (E F) in that it selects only first-level descendants.</p>

<div id="entry-examples" class="entry-examples"><div id="example-0">
<h4><span class="desc">Places a border around all list items that are children of &lt;ul class="topnav"&gt; .</span></h4>
<pre><code class="example demo-code">&lt;!DOCTYPE html&gt;

body { font-size:14px; }
&lt;/style&gt;
&lt;script src="http://code.jquery.com/jquery-latest.js"&gt;&lt;/script&gt;

&lt;body&gt;
&lt;ul class="topnav"&gt;
&lt;li&gt;Item 1&lt;/li&gt;
&lt;li&gt;Item 2
&lt;ul&gt;&lt;li&gt;Nested item 1&lt;/li&gt;&lt;li&gt;Nested item 2&lt;/li&gt;&lt;li&gt;Nested item 3&lt;/li&gt;&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;Item 3&lt;/li&gt;
&lt;/ul&gt;
&lt;script&gt;$("ul.topnav &gt; li").css("border", "3px double red");&lt;/script&gt;
