This is probably more or less true, if and only if the visibility property should have no effect on the availability of elements for user interaction. I feel that it probably ought to (and certainly must in the case of collapse); there is (IMO) no sensible way for opacity to, so this would destroy the equivalence. (One might draw an analogy with the speak and volume properties, but I'm not sure how useful this is.) Keeping the two properties separate might also be more convenient for dynamic effects. Tim Bagot
