Bootstrap 4 img-circle class doesn't seem to exist
<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>
