I'm not clear on how my proposal was taken. A part of me worry from that individual respond that he did not fully receive what I was conveying, base on the fact he only mention the CSS property animation name. Thanks for your proposal. What is the problem you're trying to solve or the difficulty you're facing? Unfortunately, I think this proposal adds complexity to the interface. For example, what is the expected behavior when the author writes the following? elem.animate({ opacity: 0 }, { 'animation-duration': '3s', 'animation': '4s' }, 5000); Likewise, allowing 'animation' seems odd since it seems to have different syntax to the 'animation' shorthand in CSS. Requiring the additional CSS argument seems unfortunate too. There are other considerations but first of all it would be good to know what problem you're seeking to solve. In general we want to reduce the surface area of the API, that is, keep it as simple as possible since once we add a feature it's very hard to remove. As a result, I'm afraid adding more ways of setting properties would need strong justification.
