title: Font Awesome icon size not increasing
body: <p>I have Font Awesome icons installed on <a href="http://www.fahaduddin.com/mattbertulli" rel="noreferrer">this</a> site. The icons size isn't increasing even after adding the class to increase size.</p>
  
  <pre><code>&lt;ul class="stay-connected-inner list-inline"&gt;
    &lt;li&gt;&lt;a href="#"&gt;&lt;i class="fa fa-twitter fa-3" aria-hidden="true"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="#"&gt;&lt;i class="fa fa-linkedin fa-3" aria-hidden="true"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="#"&gt;&lt;i class="fa fa-medium fa-3" aria-hidden="true"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="#"&gt;&lt;i class="fa fa-linkedin fa-3" aria-hidden="true"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
