body: <p>I'm trying to center the newsslider (in the div bottom-container) on this page:</p>
  
  <p><a href="http://www.luukratief-design.nl/dump/parallax/index.html" rel="noreferrer">http://www.luukratief-design.nl/dump/parallax/index.html</a></p>
  
  <p>I already have <code>text-align: center;</code></p>

  <p>Any suggestions?</p>
