title: Links do not show in hamburger menu
body: <p>I am working with bootstrap for the first time and no matter what I do, I do not get the hamburger menu right. Here is my code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="container-fluid"&gt;
    &lt;nav class="navbar navbar-light bg-faded fixed-top navbar-toggleable-sm"&gt;
      &lt;button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navnavnav"&gt;
      &amp;#9776;
      &lt;/button&gt;
      &lt;a class="navbar-brand" href="#"&gt;
        &lt;img src="http://image.jpg" width="60" height="52" class="d-inline-block align-top" alt="logo"&gt;
      &lt;/a&gt;
      &lt;div class="collapse navbar-collapse" id="navnavnav"&gt;
      &lt;ul class="nav navbar-nav" style="font-size: 1.5em"&gt;
        &lt;li class="nav-item active"&gt;
          &lt;a class="nav-link" href="#"&gt;Home &lt;span class="sr-only"&gt;(current)&lt;/span&gt;&lt;/a&gt;
        &lt;/li&gt;
        &lt;li class="nav-item"&gt;
          &lt;a class="nav-link" href="#"&gt;About Me&lt;/a&gt;
        &lt;/li&gt;
        &lt;li class="nav-item"&gt;
          &lt;a class="nav-link" href="#"&gt;Work&lt;/a&gt;
        &lt;/li&gt;
        &lt;li class="nav-item"&gt;
          &lt;a class="nav-link" href="#"&gt;Contact&lt;/a&gt;
        &lt;/li&gt;
      &lt;/ul&gt;
      &lt;/div&gt;
  &lt;/nav&gt;</code></pre>
  </div>
  </div>
