title: Bootstrap displays navbar for mobile instead desktop
body: <p>I'm usng Bootstrap4 in my Rails 5.1 project, I set up bootstrap with </p>
  
  <pre><code>gem 'bootstrap', '~&gt; 4.0.0.beta2.1'
  </code></pre>
  
  <p>I follow all the instruction and added navbar but it looks like mobile version but my desktop size is 1600px+ wide.</p>
  
  <p>What is the problem?
  Here is layout and navbar</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
    &lt;head&gt;
      &lt;title&gt;CSGO&lt;/title&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"&gt;
      &lt;%= csrf_meta_tags %&gt;
  
      &lt;%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload' %&gt;
      &lt;%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %&gt;
    &lt;/head&gt;
  
    &lt;body&gt;
      &lt;div class="container-fluid"&gt;
      &lt;%= render partial: "shared/flash" %&gt;
        &lt;%= render 'shared/nav' %&gt;
      &lt;%= yield %&gt;
  
      &lt;/div&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And the navbar partial</p>
  
  <pre><code>&lt;div class="row"&gt;
    &lt;div class="col-12"&gt;
      &lt;nav class="navbar navbar-toggleable-md navbar-light bg-faded"&gt;
        &lt;button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation"&gt;
          &lt;span class="navbar-toggler-icon"&gt;&lt;/span&gt;
        &lt;/button&gt;
        &lt;div class="collapse navbar-collapse" id="navbarTogglerDemo01"&gt;
          &lt;a class="navbar-brand" href="#"&gt;Hidden brand&lt;/a&gt;
          &lt;ul class="navbar-nav mr-auto mt-2 mt-lg-0"&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;Link&lt;/a&gt;
            &lt;/li&gt;
            &lt;li class="nav-item"&gt;
              &lt;a class="nav-link disabled" href="#"&gt;Disabled&lt;/a&gt;
            &lt;/li&gt;
          &lt;/ul&gt;
          &lt;form class="form-inline my-2 my-lg-0"&gt;
            &lt;input class="form-control mr-sm-2" type="text" placeholder="Search"&gt;
            &lt;button class="btn btn-outline-success my-2 my-sm-0" type="submit"&gt;Search&lt;/button&gt;
          &lt;/form&gt;
        &lt;/div&gt;
      &lt;/nav&gt;
    &lt;/div&gt;
  &lt;/div&gt;
