<style>

@supports not selector(:focus-visible) {

:focus {

outline: red solid 5px;

background-color: red;

}

}

:focus-visible {

outline: green solid 5px;

}

:focus:not(:focus-visible) {

background-color: red;

outline: 0;

}

</style>

This test checks that any element focused programmatically on page load will have <code>:focus-visible</code> matching enabled.

<ul id="instructions">

<li>If the element that says "I will be focused automatically" has a red background, then the test result is FAILURE. If the element has a green outline, then the test result is SUCCESS.</li>

</ul>

<br />

<div id="el" tabindex="-1">I will be focused automatically.</div>

<script>

window.addEventListener('load', () => {

el.focus();

});

async_test(function(t) {

el.addEventListener("focus", t.step_func(function() {

assert_equals(getComputedStyle(el).outlineColor, "rgb(0, 128, 0)", `outlineColor for ${el.tagName}#${el.id} should be green`);

assert_not_equals(getComputedStyle(el).backgroundColor, "rgb(255, 0, 0)", `backgroundColor for ${el.tagName}#${el.id} should NOT be red`);

t.done();

}));

}, "Programmatic focus on page load should match :focus-visible");
