Reported 2024-08-27 04:06:29 PDT
In Safari (Version 17.6 (19618.3.11.11.5)), `round()` seems to require both the rounding strategy and rounding interval parameters but both are optional according to the spec: > If <rounding-strategy> is omitted, it defaults to nearest. (Aka rounding to the nearest integer.) If the type of A matches <number>, then B may be omitted, and defaults to 1; omitting B is otherwise invalid. Source: https://drafts.csswg.org/css-values/#funcdef-round Reproduction: https://codepen.io/kleinfreund/pen/ExBRdMO Workaround: Add the default values as appropriate. The Safari dev tools show a warning icon with the label "Unsupported property value" for the two property declarations marked "fail" in the reproduction.

It is fixed on WebKit ToT, tested on 283089@main. It matches both Chrome Canary 130 and Firefox Nightly 131. Don't know which exact revision fixed it but it might be from Sam's work. (CCed him).
