While the former is an applicable (shorthand) property for highlight styles, it is not one of the highlight colors (color or background-color), so paired cascade does not apply."> <script src="support/selections.js"></script> <link rel="stylesheet" href="support/highlights.css"> <style> main { font-size: 7em; margin: 0.5em; } main::selection { /* Used values for color and background-color should be the UA defaults, usually like black on blue or white on blue, *not* initial on initial (like unhighlighted content). */ text-decoration: none; } </style> <p>Test passes if the text below appears to be highlighted. <main class="highlight_reftest">quick</main> <script>selectNodeContents(document.querySelector("main"));</script>
