title: Fade out animation when ng-if = false
body: <p>Is there any way to animate with fade out when <code>ng-if="false"</code> instead of instantly hide the HTML element?</p>
  
  <p>I can fade-in when <code>ng-if="true"</code> but can't when <code>ng-if="false"</code>. When <code>ng-if="true"</code> I'm using <a href="http://daneden.github.io/animate.css/" rel="noreferrer">Animate.css</a> library to animate with fade-in.</p>
