title: Stop div container from resizing
body: <p>I have two columns in an html page, one is floated right and the other is floated left.
  I have set the height of both containers to 100% and the width of both containers to 50%.  I want the two containers to fit the entre window.  When the user re-sizes the window horizontally I don't want the content to resize.  How can i achieve this?</p>
  
  <p>Thanks</p>
