The issue with shorthands, I think, is whether the author expects individual properties to animate when shorthands are used in transition-property, and when the individual properties as changed via shorthand rules. I would. If I have 'margin' as the transition-property, and then I change 'margin-top', then it should animate. The other margin would also be animating in theory, but with the same beginning and ending values, who would know? If I did it the other way around, and had 'margin-top' as the transition-property, and then changed 'margin' to something that was different on all four sides, then I think only 'margin-top' would animate, but the other margins would just jump instantly to their new values.Received on Wednesday, 7 July 2010 06:41:40 UTC
