title: Remove style from prev/next element when hovering on element
body: <p>Example:</p>
  
  <p><a href="http://jsfiddle.net/JUmHG/3" rel="nofollow">http://jsfiddle.net/JUmHG/3</a></p>
  
  <p>When mouse is over on a LI, the top/bottom border of the LI becomes transparent (replaced by background-color).</p>
  
  <p>But also the bottom-border of the previous LI and the top-border of the next LI must be transparent as well. Can this be done with CSS ?</p>
