title: Tell me how to do the semi liquid layout without javascript, i feel I'm missing something simple
body: <p>Okay, first off I'm supporting back to IE7, so box-sizing is out.</p>
  
  <p>I've got a fixed size header and footer (say 80px each) positioned to the top and bottom of the window, respectively.</p>
  
  <p>I want a div to take up all he space between, regardless of window size. Easy breezy with JavaScript, but is there a way to do it with just CSS?</p>
