      <h2>Simple CSS Parallax Effect</h2>
      <p>When hovering the section above, the headline and the background slide horizontal - similar to a js based parallax. I used six absolute positioned spans (.blind) to get the position of the mouse. According to each position, the CSS of the following h1 and h1:after is changed. The idea is based on Fabrice Weinbergs concept of a <a href="https://codepen.io/FWeinb/pen/GrpqB" target="_blank">Direction aware hover pure CSS</a>.</p>
      <p>The layout is inspired by some dribbble shots of <a href="https://dribbble.com/lauralin" target="_blank">Laura</a> and the bull is taken from <a href="http://etc.usf.edu/clipart/" target="_blank">ClipArt ETC</a>.</p>
