title: Get height of DOM element in LESS/CSS
body: <p>I have a list of elements which I want to delete with an onclick. It give the element an extra css class which hides the element. The class in css says that the element will dissapear using an animation (FadeOutLeft) using <a href="http://daneden.me/animate/" rel="nofollow">animate.css</a>. </p>
  
  <pre><code>@keyframes fadeOutLeft {
  0% {
      opacity: 1;
      transform: translateX(0);
  }
  100% {
      opacity: 0;
      transform: translateX(-20px);
  }
  </code></pre>
  
  <p>}</p>
  
  <p>The problem is that I cant use a "display:none" at 100%. I don't know why but it just doesnt work. So what I want to do is give the 100% a margin-bottom:-{height of the current element}px and also I also want to set the "translateX()" to that value. So what I have to do is get the height of the element there in less. Is this possible with using javascript In Less?</p>
