  <style>
  div
    {
      color: transparent;
      float: left;
      font-size: 16px;
      padding: 8px;
    }

  div#blue-rectangle
    {
      background-color: blue;
      margin: 8px;
      width: 6em;
    }

  div#orange-rectangle
    {
      background-color: orange;
      height: 0px;
      width: 12em;
    }
  </style>

  <p>Test passes if the orange rectangle and blue rectangle do not overlap.

  <div id="blue-rectangle">Some text in a blue rectangle.</div>

  <div id="orange-rectangle">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore.</div>
