title: Font awesome 5 pseudo-class not working with my kit
body: <p><strong>Note: I haven't added my kit number here</strong></p>
  
  <p>I am using the Font awesome 5.  I got kit script after login in the font awesome poral. My issue is, If I added below code</p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html&gt;
    &lt;head&gt;
      &lt;!-- Place your kit's code here --&gt;
      &lt;script src="https://kit.fontawesome.com/kitnumber.js" crossorigin="anonymous"&gt;&lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;i class="fas fa-thumbs-up fa-5x"&gt;&lt;/i&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>then I am getting my icon but if I use pseudo-class then I am not getting the icon.</p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html&gt;
    &lt;head&gt;
      &lt;!-- Place your kit's code here --&gt;
      &lt;script src="https://kit.fontawesome.com/kitnumber.js" crossorigin="anonymous"&gt;&lt;/script&gt;
      &lt;style type="text/css"&gt;
        .f_icon:after{
           content: "\f164";
          font-family: 'Font Awesome 5 Free';
          font-weight: 900;
          display: inline-block;
          position: absolute;
          top: 30%;
        }
      &lt;/style&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;div class="f_icon"&gt;&lt;/div&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>But the above code is working if I add font awesome css without my kit. </p>
