Implementations also must not start a transition when the computed value changes because it is inherited (directly or indirectly) from another element that is transitioning the same property. sure sound like the computed value is what matters. However the start of section 3 still talks about "the value"; it should probably explicitly say "computed value". > some simple testing seems to show that webkit uses specified value: Yeah, I think we decided a while back that that's not what we want here, since it makes transitions on things like percentage widths when ancestors are resized not really work that well. -Boris
