I think the "(either on its own or via a shorthand that contains it)" makes the spec reasonably clear that that's the case. > In other words, should this be equivalent to (a): > > transition-property: border-top-width, border-bottom-width, border-left-width, border-right-width; > transition-duration: 3s, 3s, 3s, 1s; > > Or (b): > > transition-property: border-top-width, border-right-width, border-bottom-width, border-left-width, border-right-width; > transition-duration: 3s, 3s, 3s, 3s, 1s; The latter, although I don't see how the difference is detectable. -David -- L.
