<p>If you are on a device without a cursor, skip this test.
<p>Otherwise, if the cursor does not look like a red and a green arrow, the test has failed.
<p>Place the cursor so that the tip of the <strong>red arrow</strong> is on the <strong>green box</strong>, then click.
<p>If nothing happens when you click, the test has failed.
<div onclick="pass(event)"></div>
<p id=fail>The test has failed.
<p id=pass>The test passes.

function pass(e) {
  document.getElementById("pass").style.display="block";
  e.stopPropagation();
}
function fail() {
  document.getElementById("fail").style.display="block";
