heights on ordered/unordered lists not being returned
<p>Does jquery handle ordered lists height? I'm getting NULL returned.</p>

<p>js</p>

<pre><code>  var highestCol = $('ol.mostrecent').height();
  console.log(highestCol);
</code></pre>

<p>html </p>

<pre><code>    &lt;ol class="mostpopular"&gt;
