title: Why wont Font-Awesome icon load in my Rails App on Heroku?
body: <p>I'm learning how to build rails apps, so bear with me on this question.</p>
  
  <p>I've loaded font-awesome using the 'font-awesome-sass' gem. </p>
  
  <p>In my CSS file, I load font-awesome:</p>
  
  <pre><code>@import "font-awesome-sprockets";
  @import "font-awesome";
  </code></pre>
  
  <p>This works great when I test my app locally. I'm using the <code>fa-users</code> icon. I call this in my html page using:</p>
  
  <pre><code>&lt;%= link_to root_path, class:'navbar-brand' do %&gt;
    &lt;i class="fa fa-users"&gt;&lt;/i&gt;
    Title
  &lt;% end %&gt;
  </code></pre>
  
  <p>However, when I deploy my app to Heroku, the fa-user icon turns into a square.</p>
  
  <p>How can I fix this?</p>
