For the record, Gecko doesn't implement any CSS keywords or units that contain only the characters a-f (treating any -moz- prefixes as not present). However, if I double the search range to a-l, then Gecko implements the following units: ch deg and the following keywords: all cell deck field fill hide So I don't think it's an unrealistic worry that we might have some such keywords in the future. (Consider, for example, 'fade'.) More importantly, though, if Gecko encounters an ambiguity between color and keyword in a property that accepts both, it will pick the keyword. -David -- ? L.
