title: Can ngAnimate be used without defining CSS3 classes or JavaScript?
body: <p>Is it possible to use <a href="http://code.angularjs.org/1.1.4/docs/api/ng.directive%3angAnimate" rel="nofollow">ngAnimate</a> without any CSS3 or JavaScript? Let's say if you simply need to toggle the opacity, can you just do it in the markup? </p>
  
  <pre><code>&lt;div ng-show='foo == 'yes'' ng-animate="show: 'opacity:1', hide: 'opacity:0'" &gt;
  &lt;/div&gt;
  </code></pre>
