title: Reset positioning HTML / CSS
body: <p>I have a problem. I tried to create a special effect in the background of my website for which I used some <code>div</code>which are overlaped. Now the page with the content itself should be placed over this background again. But if I set it to <code>position: absolute</code> and add <code>top:0</code> the page isn't centered again cause the <code>margin:0 auto</code> doesn't work with the absolute position.</p>
  
  <p><a href="http://eckstein.be/r/position-problem/" rel="nofollow">I put it online, so you can have a look on it...</a></p>
  
  <p>The dark grey navigation bar should be at the top of the site. How can I do this? I'm really confused rightnow... Thanks for any help!</p>
