title: Bootstrap 4 Hamburger Menu Not Showing Navbar
body: <p>This is for my mobile sized site.  When I click the hamburger menu, the Navbar does not appear.  My <code>data-target</code> matches the <code>nav id</code> so I'm not sure why it isn't working.</p>
  
  <pre><code>&lt;section id="nav"&gt;
          &lt;nav class="navbar navbar-light navbar-expand-md py-2"&gt;
              &lt;a href="index.html"&gt;
                  &lt;img src="./img/logo.png" class="img-fluid mw-121 height: auto" alt="Logo"&gt;
              &lt;/a&gt;
              &lt;button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarLinks"&gt;&lt;span
                      class="navbar-toggler-icon"&gt;&lt;/span&gt;
              &lt;/button&gt;
              &lt;div class="collapse navbar-collapse justify-content-end" id="navbarLinks"&gt;
                  &lt;ul class="nav"&gt;
                      &lt;li class="nav-item"&gt;
                          &lt;a class="nav-link" href="index.html"&gt;Home&lt;/a&gt;
                      &lt;/li&gt;
                      &lt;li class="nav-item"&gt;
                          &lt;a class="nav-link" href="flavors.html"&gt;Flavors&lt;/a&gt;
                      &lt;/li&gt;
                      &lt;li class="nav-item"&gt;
                          &lt;a class="nav-link" href="details.html"&gt;What's Included&lt;/a&gt;
                      &lt;/li&gt;
                      &lt;li class="nav-item"&gt;
                          &lt;a class="nav-link" href="reserve.html"&gt;Reserve Today&lt;/a&gt;
                      &lt;/li&gt;
                      &lt;li class="nav-item"&gt;
                          &lt;a class="nav-link" href="faq.html"&gt;FAQ&lt;/a&gt;
                      &lt;/li&gt;
                  &lt;/ul&gt;
              &lt;/div&gt;
          &lt;/nav&gt;
