title: Is there a GUI framework that uses HTML and CSS to build GUIs?
body: <p>I mean, other than a browser, of course -- I'm talking about building native applications with HTML and CSS -- not web applications, but <em>real</em> native GUIs.</p>
  
  <p>I wonder if such a thing exists?</p>
  
  <p>And what do you think of such a beast? What would the pros/cons of such a system be?</p>
