title: CSS pseudo after/before using content or background for img?
body: <p>As for pseudo-elements <code>:after</code>/<code>:before</code> there are apparently two ways if I want to display image there:</p>
  
  <ol>
  <li>using <code>background-image:url(imgurl.png);</code></li>
  <li>using <code>content:url(imgurl.png);</code></li>
  </ol>
  
  <p>Are both ways correct and valid? Why should I be using one way over another?</p>
  
  <p>Apparently using the second method you cannot set the picture properties like size. But first method is generaly more taught on internet.</p>
  
  <p>Ideas?</p>
