  :focus-visible {
    outline: solid thick green;
  }

  :focus:not(:focus-visible) {
    outline: none;
    background-color: red;
  }
</style>

This test checks that using a modifier key does not make the element to stop matching <code>:focus-visible</code>.
<ol id="instructions">
  <li>If the element that says "Focused" has a red background, then the test result is a FAILURE.</li>
  <li>Press the Ctrl key.</li>
  <li>If the element keeps the green outline and has not a red background, then the test result is SUCCESS.</li>
</ol>
<p id="warning">Your user-agent does not support <code>:focus-visible</code> pseudo-class, please SKIP this test.</p>

<div id="target" tabindex="0">Focused</div>
