Should see a green square below.
<div id="foo"></div>
<script>
test(function() {
let foo = document.getElementById('foo');
assert_equals(getComputedStyle(foo).backgroundColor, "rgb(255, 0, 0)");
let style = document.createElement('style');
style.textContent = "#FoO { background: green; }";
document.body.appendChild(style);
assert_equals(getComputedStyle(foo).backgroundColor, "rgb(0, 128, 0)");
}, "Style should've changed to a green background");
