title: Center Div inside another (100% width) div
body: <p>Quite a "simple" problem here and not sure why it's being so complicated.</p>
  
  <ol>
  <li>Have a 100% (width) sized div.</li>
  <li>Have another div positioned in the middle of this div (sized 940px width)</li>
  </ol>
  
  <p>Any ideas? :) </p>
