title: Can a div have multiple classes (Twitter Bootstrap)
body: <p>Can a div tag have two classes?</p>
  
  <p>I am using twitter bootstrap, and there are two predefined classes that I would like to use.</p>
  
  <p>One is an <code>active</code> class that I would like to use on a <code>dropdown-toggle</code> within a nav bar.</p>
  
  <p>What is the best way of approaching this in the html, with out overriding the css.</p>
