title: Implementing GTA5-parallax-pen from codepen
body: <p>I found this neat pen on codepen <a href="http://codepen.io/simooo/pen/egatA" rel="nofollow">http://codepen.io/simooo/pen/egatA</a> and wanted to implement it on my website. But somehow I can't get it working. I tried also using only the code (with html5 markup) but that didn't help either.
  I copied it to jsfiddle (jsfiddle.net/2mm6u/), to see if I could find the problem experimenting with it but the Fiddle also doesn't work.</p>
  
  <p>So I hope to find some help here, as I'm new to the whole parallax-effects.</p>
