title: How do I make a div’s scrollbar always visible?
body: <p>How do I make my <code>div</code>’s scrollbar always visible?</p>
  
  <pre><code>.el {
    height: 100px;
    overflow: scroll;
    position: relative;
  }
  </code></pre>
  
  <p><code>overflow: scroll</code> is not working. It seems my browser’s native behavior does not allow that. (I’m on macOS.)</p>
  
  <p>Is there some workaround?</p>
  
  <p>P.S. The scroll bar is visible on hover, but I need it to always be visible.</p>
