Animation delay should support CSS counters as part of their value, like -webkit-animation-delay: counter(row) "s"; Use case: Fading in a bullet list, one item at a time. Instead of declaring delays for every single list item, the counter could be used. URL: http://jsbin.com/ewidoj
This is a good suggestion, but it really needs to be added to the spec before we could implement it. Email public-fx@w3.org
Thanks, I have sent the suggestion to the public-fx list.
This request seems more for a generic way to use counters as values, perhaps via calc(). I don't think it's specific to animations, so closing this bug. Please file a new one if spec discussions warrant it.
