title: Height, percentages, animate issues
body: <p>Well I have this: <a href="http://codepen.io/seraphzz/pen/HfqBy" rel="nofollow">http://codepen.io/seraphzz/pen/HfqBy</a></p>
  
  <p>OK, I've used animate(); before and it has worked perfectly. I just don't know why it doesn't this time.(It's a long image that I want to move on hover)</p>
  
  <p>Also, I'm trying to make it responsive using percentages but It won't get any height if I don't use pixels.</p>
  
  <p>Can you guys help me with that?
  Thanks in advance!
  Best regards!</p>
