We're aware that this is terribly under-specified. And it is quite complicated, since there are so many things to consider, and CSS doesn't really say itself when *exactly* style updates happen. Any advice you have here is appreciated. > Similarily other changes may occur > while a transition is in progress, what happens then is not clear at all > absent such definitions. We're clarifying what happens when the values of a transition change mid- transition. If they are changes to the properties of the transition (say, extending the duration) then they have no effect: the values are snapshotted when the transition starts. If they are changes to the property that is being transitions, then a new transition starts to the changed value from the current value (which will be part way through a transition). Some people want the ability to auto-reverse a transition, but we're not quite ready to propose that at the moment. Dean
