title: Position relative DIVS
body: <p>I always see code like this:   </p>
  
  <pre><code>#container {
      background:#000000 none repeat scroll 0 0;
      display:block;
      overflow:hidden;
      position:relative;
      width:100%;
  }
  </code></pre>
  
  <p>I thought position relative is used to accommodate the div relatively to its parent element using the CSS proprieties left right top and bottom (px). What's the point of using it alone like the example below? Which other properties are being affected by position relative?</p>
