title: How can I fade in and out the visibility of a DIV using ng-show with AngularJS 1.3 beta?
body: <p>My code looks like this:</p>
  
  <pre><code>&lt;div class="block-border"
       data-ng-show="qty &gt; 0"&gt;
     xxx
  &lt;/div&gt;
  </code></pre>
  
  <p>I know there have been a lot of changes with Animation in AngularJS. Can someone tell me the easiest way for me to make it take 500ms to show and 50ms to hide the xxx when the value of qty changes. Note that I am using the very latest AngularJS.</p>
