> Mathematically, "positive" usually means zero or greater, which is what I was thinking of, although depending on how the CSS parser handles -0, you might need some extra text in there. That's not really true in my experience? Zero is neither positive nor negative, and there's a lot of stuff backing that up: the relatively common usage of "non-negative" in precise technical contexts, the implementations of sign() functions in various languages, the fact that +0 and -0 are mathematically equivalent, etc. CSS has been pretty precise about this, because we've gotten bug reports about "why isn't 0 valid?" when we were imprecise and just used "positive". At best, whether 0 is considered "positive" or not is ambiguous and context-sensitive. -- GitHub Notification of comment by tabatkins Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/355#issuecomment-237291829 using your GitHub account
