| This test checks that using the Tab key to navigate focus to an element triggers <code>:focus-visible</code> matching. |
| <ol id="instructions"> |
| <li>If the user-agent does not claim to support the <code>:focus-visible</code> pseudo-class then SKIP this test.</li> |
| <li>Use the TAB key on the keyboard to focus the element below that says "Focus me."</li> |
| <li>If the element does not have a blue outline, then the test result is FAILURE. If the element has a blue outline, then the test result is SUCCESS.</li> |
| </ol> |
| <br> |
| <div id="el" tabindex="0">Focus me.</div> |
