title: jQuery animates (addsClass) to only one <a> tag instead of all?
body: <p>I have this fiddle here: <a href="http://jsfiddle.net/CS5Bb/2/" rel="nofollow">http://jsfiddle.net/CS5Bb/2/</a></p>
  
  <p>Alls I want to happen is when I hover over an <code>a</code> tag it animates adding a bit of padding and a border on the left. It does do this for just the first one (Home) but not for the others which are (as far as I can tell) identical.</p>
  
  <p>I feel like I'm missing something really obvious here. Like, I'm going to slap my forehead when I find out why. But with the jQuery being only 4 lines wrong I really can't see where I'm going wrong.</p>
