title: remove specific classes within a div
body: <p>I'm trying to remove all specific classes within a specific div. I've tried various jQuery code and cannot get it working. I want to remove "remove all of this" below</p>
  
  <pre><code>&lt;div id="commRollover"&gt;
  
  &lt;div class='nRegions' style='display:none;' id='Belgium' &gt;&lt;b&gt;&lt;em&gt;Belgium&lt;/em&gt;&lt;/b&gt;&lt;BR&gt;&lt;BR&gt;                                                    
  
  &lt;div class='commIntro'&gt;remove all of this&lt;/div&gt;
  &lt;BR /&gt;&lt;/div&gt;
  &lt;BR /&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I tried the following:</p>
  
  <pre><code>$("#commRollover").removeClass("commIntro");
  </code></pre>
