title: Efficiences of using ng-class-odd?
body: <p>Is it better to use </p>
  
  <pre><code>ul li:nth-child(odd){}
  ul li:nth-child(even){}
  </code></pre>
  
  <p>instead of ng-class-odd and ng-class-even ? </p>
  
  <p>i.e is it more efficient to use css than javascript for alternate coloration of rows in a "ul" list </p>
  
  <p>My list has anywhere between 30-200 rows</p>
