title: Add font-awesome icon to a series of buttons
body: <p>I know I can specifically add a font awesome to a button like this:</p>
  
  <pre><code>&lt;a href="#" class="btn btn-default"&gt;Some text &lt;i class="fa fa-chevron-right"&gt;&lt;/i&gt;&lt;/a&gt;
  </code></pre>
  
  <p>But is there a way I can create a CSS class so that the icon is automatically inserted for all buttons?</p>
