title: Bootstrap - Center content vertically and horizontally inside container-fluid
body: <p>Just like the title says, in Bootstrap 4, I can't figure out how to center content inside a column that's inside .container-fluid.</p>
  
  <p>Here's my code, can someone please let me know what I did wrong?</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;link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-beta.2/css/bootstrap.css" rel="stylesheet" /&gt;
  &lt;div class="container-fluid"&gt;
    &lt;div class="row"&gt;
      &lt;div class="col-md-4 my-auto mx-auto"&gt;
        &lt;div class="mx-auto"&gt;
          &lt;h1 class="mb-5"&gt;This is a title
          &lt;/h1&gt;
          &lt;p class="mb-5"&gt;Lorem ipsum&lt;/p&gt;
          &lt;a href="#"&gt;Click me&lt;/a&gt;
        &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="col-md-8"&gt;
        &lt;p&gt;Something else that's not important but needs to be here &lt;/p&gt;
      &lt;/div&gt;
    &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Why doesn't the .mx-auto work and what can I use instead of it?</p>
