Would we support CSSStyleValue.parse, CSSStyleValue.parseAll or some same API ?

Glad to see someone is doing this. Have you done any performance testing to see what the fastest path of style updates is in the browser? That kind of data is really hard to find.

The readme says that this is an in-progress polyfill. But there seems to be no activity since 2018 on this repo. So what is the state of the polyfill ? Is it usable or is it still incomplete ?

Hi, @csstools. I began work converting this to TypeScript. Would that be cool? I can also help maintain.

For example, in the official spec, dividing the dividend x by the divisor y where y is Number yields a CSSUnitValue – when you pass an object as the divisor (such as CSS.px), the official spec yields a CSSMathProduct.

However in the case of this polyfill, if the divisor is a Number then you simply yield null which doesn't seem to conform to how the implementation should be.

CSS.px(10).div(2); // CSSUnitValue {value: 5, unit: "px"} (official)
CSS.px(10).div(2); // null (polyfill)

I would fix it myself with a PR, but I'm not entirely sure the best way to fix up the div method. Whether you have a preference for one way over another 👍
