title: make a scrollbar always visible in a div - chrome
body: <p>I've implemented infinite scrolling for the first time, but I can't get the scrollbar to show up initially when there is no overflow. I tried this in chrome:</p>
  
  <pre><code>#scrollarea-invalid {
  overflow-y: scroll !important;
  height: 350px;
  }
  </code></pre>
  
  <p>how can I make the scrollbar always show up in this div, even if the content is less than 350px in this div?</p>
