title: Node.js - generate ugly class names
body: <p>Is there a way to generate ugly class names? I mean if there's a plugin that I could use to replace <code>.top-header</code> class with <code>.a9ev</code> in my css. Also, would be great if class name in my html was also changed</p>
  
  <p>How big sites like facebook or google do this?</p>
