title: Display down arrow inside a span class in html just like a plus in the code displays?
body: <p>I am wondering since the class "fa fa-plus"
  displays the + sign in the navigation bar dropdown menu, how I would display the down arrow? Here is my current HTML:</p>
  
  <pre><code>  &lt;span class="fa fa-dropdown"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>I am using <a href="https://fontawesome.com" rel="nofollow noreferrer">font awesome</a>.</p>
