title: Bootstrap 4 vertical align text won't center on card
body: <p>Trying to vertically align the text center in the following card:</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 rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous"&gt;
  
  &lt;div class="row text-center h-100"&gt;
    &lt;div class="col-md-3 text-center my-auto"&gt;
      &lt;div class="card card-block justify-content-center" style="height: 120px"&gt;
        &lt;div class="card-body"&gt;
          This is some text within a card body.
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I am fully aware of the many similar questions here, however I tried various solutions and none of them seems to work for my cards.</p>
  
  <p>I tried "my-auto" on parent, card, and card-body. I tried "d-flex align-items-center h-100" and "justify-content-center". Also tried to play around with the display property. What am I missing? </p>
