title: Change divs associated to links on hover
body: <p>I have a list of links on one side and given a div outside of that list, I'd like to change the content of that div by hovering on the links so that for each link I can display a correspondent div with some info inside.</p>
  
  <p>An example of what I'd like to achieve is on this page:</p>
  
  <p><a href="http://www.darley.co.uk/stallions/our-stallions" rel="nofollow">http://www.darley.co.uk/stallions/our-stallions</a></p>
  
  <p>As you can see, if you hover on a horse's name on the list, the div on the right changes to display the info relative to that horse.</p>
  
  <p>I have checked the code of that page but I can't see any Javascript associated with this effect and there's nothing on the HTML code either.</p>
  
  <p>Any idea on how I can replicate that effect?</p>
  
  <p>Thanks in advance for your help!</p>
