title: FontAwesome Icons don't show up
body: <p>I have this in my <code>&lt;head&gt;</code> code:</p>
  <pre><code>&lt;script href=&quot;https://kit.fontawesome.com/a076d05399.js&quot;&gt;&lt;/script&gt;
  </code></pre>
  <p>and in some of my buttons I have these:</p>
  <pre><code>&lt;div class=&quot;scroll-up-btn&quot;&gt;
     &lt;i class=&quot;fa fa-arrow-up&quot; aria-hidden=&quot;true&quot;&gt;&lt;/i&gt;
  </code></pre>
  <p>However, they don't show up. Why? The icons should show up, I've got over 6 of them and none shows up.</p>
