title: How to stretch this CSS menu to 100%
body: <p>Here's a fantastic <a href="http://www.devinrolsen.com/wp-content/themes/dolsen/demos/css/infinite-sub-menu/" rel="nofollow noreferrer">CSS menu</a>:</p>
  
  <p>The only disadvantage its not stretched to 100%... if it has 2 elements, it should be 50%/50%, if 4 items then 25%/25%/25%/25% just like they were table cells. How to do that? I'm new to CSS.</p>
