Thanks for the additions. The page https://developer.mozilla.org/en-US/docs/Web/CSS/background-clip#specifications is currently targeting spec version "Module Level 3", and the syntax for background-clip: text may change, there are open discussions about it: https://drafts.csswg.org/css-backgrounds-4/#propdef-background-clip.

We may want to wait until the open questions on this spec are resolved. The linked PR (#201) has a discussion about this already.
