I And the lack of it in media queries makes media queries quite difficult to work with. For example, it's hard to write a pair of style sheets for: * screen, less than or equal to 400px * screen, greater than 400px without either (a) making assumptions about pixel rounding that probably aren't valid in general or (b) dealing with the fact that both style sheets will apply at exactly 400px. I think it's a pretty important use case for @supports, especially in cases where authors end up testing prefixed properties (since they'll want to nest an "or" inside an "and"). -David -- 𝄞 L.
