circle-accepts-closest-corner circle() accepts the closest-corner radius keyword. spec ↗ script
circle-accepts-farthest-corner circle() accepts the farthest-corner radius keyword. spec ↗ script
ellipse-accepts-corner-keywords ellipse() takes two radii, and both accept the corner keywords. spec ↗ script
side-keywords-still-accepted The pre-existing closest-side and farthest-side keywords must keep working: this is an addition, not a replacement. spec ↗ script
corner-keywords-work-in-shape-outside The keywords work in shape-outside, not only clip-path. spec ↗ script
corner-keywords-work-in-offset-path The keywords work in offset-path, completing the set of properties that take a basic shape. spec ↗ script
radial-gradient-has-always-accepted-them radial-gradient accepted these keywords long before shapes did. This is the parity being fixed, and asserting it pins the reference point rather than assuming it. spec ↗ script
invalid-radius-keyword-rejected The keyword set is closed: a plausible-looking value outside it must not parse, or the parser would be accepting nonsense as a shape. spec ↗ script
