title: 100% width sticky footer + header, but centered 3 column content with height 100%?
body: <p>I am trying to create a webdesign with a full width fixed menu, a full width header, 960px wide centered content with 3 columns (each with the height of 100%) and a full width sticky footer.</p>
  
  <p>In all working examples I have seen header, content and footer is the same width.</p>
  
  <p><em>(edited) My problem is to make the columns stretch to full height of the screen, from the bottom of the header to the top of the footer, at any screen size.</em></p>
  
  <p>I have made an example of what I am trying to achieve: <a href="http://muku.dk/example.jpg" rel="nofollow">http://muku.dk/example.jpg</a></p>
  
  <p>Is this possible with CSS?</p>
