title: How to test for nth-child using Modernizr?
body: <p>I'm trying to use modernizr to test for <code>:nth-child</code> browser support but I'm not sure how to do it, I found this one <a href="http://jsfiddle.net/laustdeleuran/3rEVe/" rel="noreferrer">http://jsfiddle.net/laustdeleuran/3rEVe/</a> which tests for <code>:last-child</code> but I don't know how to change it to detect <code>:nth-child</code> (I was also thinking about using it like that since I believe that browsers that don't support <code>:last-child</code> don't support <code>:nth-child</code> either but I'm not sure)</p>
  
  <p>Can you guys help me? Thanks in advance!</p>
