<title>CSS Pseudo-Elements Test: paired cascade: UA default highlight colors are not used when highlight pseudo has declared color value of unset</title>
<link rel="author" name="Delan Azabani" href="mailto:dazabani@igalia.com">
<link rel="help" href="https://drafts.csswg.org/css-pseudo-4/#highlight-cascade">
<link rel="match" href="highlight-paired-cascade-005-ref.html">
<meta name="assert" value="This test verifies that setting color to unset on ::selection suppresses any UA non-initial used value for background-color. The unset value is defined as both “treated as [inherit or initial depending on whether the property is inherited]” and “effectively erases all declared values occurring earlier in the cascade [(inclusive)]”, which are normally equivalent, but under paired cascade, the former wins.">
<script src="support/selections.js"></script>
<link rel="stylesheet" href="../support/highlights.css">
<style>
main {
font-size: 7em;
margin: 0.5em;
}
main::selection {
/*
Used background-color should be initial (transparent).

*/
color: unset;
}
</style>
<p>Test passes if the text below does not appear to be highlighted.
