jquery addClass adding subclass not working
<p>this is my 1st time posting here, so thanks to everyone who can give me some advice!</p>

<pre><code>&lt;html&gt; 
&lt;head&gt; 
  &lt;style&gt; 

  &lt;/style&gt; 
  &lt;script src="jquery-1.5.2.js"&gt;&lt;/script&gt; 
&lt;/head&gt; 
&lt;body&gt; 

&lt;div 
class="super"
style=" 
border: solid black 1px; 
height:100px;
width:100px;
"&gt;
&lt;/div&gt; 

&lt;div
class="super .eight"
style=" 
background: blue;
"&gt;
&lt;/div&gt;



&lt;script&gt; 
  $(".super").click(function () {
      $(this).addClass(" .eight");
});
&lt;/script&gt; 

&lt;/body&gt; 
&lt;/html&gt; 
</code></pre>

<p>So basically the problem is that I want to add for example a background or some other type of element onto class that is already defined as super. I am trying to use subclasses but it does not seem to be working.</p>

<p>Please ask me if there is anything unclear, I apologize if there is. </p>
