title: Is it possible to combine classes in CSS?
body: <p>Suppose I have a en element <code>&lt;div clas="foo bar foobar"&gt;[stuff]&lt;/div&gt;</code> and I want to replace these three classes with one class (SuperFoo).</p>
  
  <p>While I could find out how foo, bar and foobar are defined, and use each of those elements:</p>
  
  <p><code>.SuperFoo { color : red }</code> and so on,  is it possible to define SuperFoo in terms of foo, bar and foobar?</p>
  
  <p><code>.SuperFoo { foo bar foobar}</code>?</p>
  
  <p>How can I do this?</p>
