title: How to create button in navbar with icon-bars with bootstrap?
body: <p>I am new to bootstrap. I want to create a button in navbar that has three icon-bars.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;button type="button" class="navbar-btn btn-default pull-right"&gt;        
      &lt;span class="icon-bar"&gt;&lt;/span&gt;  
      &lt;span class="icon-bar"&gt;&lt;/span&gt;  
      &lt;span class="icon-bar"&gt;&lt;/span&gt;    
  &lt;/button&gt;
  </code></pre>
  
  <p>Above creates a button but it's very small and has no icon-bars. What am I doing wrong?</p>
