title: Sidebar toggle button not showing 3 bars while viewing in mobile
body: <p>While I open a page in mobile, the sidebar toggle is not looking like a menu, it is looking like a box. I'm using the adminlte theme.</p>

  <p>Code:</p>
  
  <pre><code>&lt;a href="#" class="sidebar-toggle" data-toggle="offcanvas" role="button"&gt;
      &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&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;/a&gt;
  </code></pre>
