#test {
  position: absolute;
  width: 100px;
  height: 100px;
  background: orange;
  overflow: hidden;
  resize: both;

<p>Enlarge the orange box so that it at least covers the blue box entirely, then press the “done” button.</p>
<!-- There's no actual need to cover the whole box,
  but doing so makes sure that the user has resized in both dimensions -->

<button onclick="verify()">done</button>
