title: Bootstrap 4 img-circle class doesn't seem to exist
body: <p>I'm writing a website in HTML5 and Bootstrap 4 and I'm trying to turn a square image into a circle. In Bootstrap 3 this was easily do-able with <code>.img-circle</code>, but now I can't seem to get it to work and I can't find any answers online.
  Has Bootstrap dropped the img-circle class or is my code messed up?</p>
  <p>It goes something like this:</p>
  <pre><code>&lt;!-- Within a tab-content div --&gt; 
  &lt;div class=&quot;col-xs-7&quot;&gt;
      &lt;img src=&quot;img/gallery2.JPG&quot; class=&quot;img-circle&quot; alt=&quot;HelPic&quot;&gt;
  &lt;/div&gt;
  </code></pre>
  <p>Hope somebody can help me out :)</p>
