<p class="desc"><strong>Description: </strong>Select all elements that have no children (including text nodes).</p>
<div class="longdesc">
<p>This is the inverse of <code>:parent</code>. </p>
<p>One important thing to note with :empty (and :parent) is that child elements include text nodes.</p>
<p>The W3C recommends that the <code>&lt;p&gt;</code> element have at least one child node, even if that child is merely text (see http://www.w3.org/TR/html401/struct/text.html#edef-P). Some other elements, on the other hand, are empty (i.e. have no children) by definition: &lt;input&gt;, &lt;img&gt;, &lt;br&gt;, and &lt;hr&gt;, for example.</p>
</div>
<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Finds all elements that are empty - they don't have child elements or text.</span></h4>
<pre class="prettyprint"><code class="example demo-code">&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
  &lt;style&gt;

  td { text-align:center; }
  &lt;/style&gt;
  &lt;script src="http://code.jquery.com/jquery-1.7rc2.js"&gt;&lt;/script&gt;

    &lt;tr&gt;&lt;td&gt;TD #2&lt;/td&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt;

    &lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;td&gt;TD#5&lt;/td&gt;&lt;/tr&gt;

&lt;script&gt;$("td:empty").text("Was empty!").css('background', 'rgb(255,220,200)');&lt;/script&gt;
