title: Css - Can't change vertical position on <a> tag
body: <p>At my <a href="http://mmd3e12dae42.keaweb.dk/test/index.html" rel="nofollow">website</a> i want to move the a tag(the black box) down to the middle, but i cant get it to work. I must not affect the other elements on the page.
  When i add top: 50%; in firebug it moves down to middle as i want it to, but i can't make it work for the real site.
  The CSS for the element:</p>
  
  <pre><code>.section {
      width: 100px;
      height: 100px;
      background-color: black;    
      position: relative;
      margin-left: 720px;
      top: 50%;
  }
  </code></pre>
