title: Bootstrap 4 - container class and rounded corners?
body: <p>How can I have achieve a div which has a container class from Bootstrap but also has rounded corners?  </p>
  
  <pre><code>&lt;div class="container rounded"&gt;
    &lt;div class="row"&gt;
       &lt;div class="col"&gt;Approver:&lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>When I use the above code, my corners still appear to be square however Bootstrap 4 documentation states that the "rounded" class should take care of rounded corners?  </p>
