title: Make pseudo element's height the same as the element it is attached to
body: <p>I have a very quick question but I don't know how to phrase it optimally to get a relevant search result. Basically I have a <code>&lt;div class="element"&gt;&lt;/div&gt;</code> with <code>.element{height:100px}</code>. I'm adding a <code>after</code> pseudo element to my <code>.element</code> with the same height but I'm not sure how to reference the original height in the pseudo one.</p>
  
  <p>Thank you. (I hope what I just said makes sense)</p>
