Because filesize is at a premium, and not enough people (80-95%) need this feature almost every time they use jQuery (80-95%). That's the point of plugins. I wrote something on the subject some time ago, and I think it sums it up well. See
http://groups.google.com/group/jquery-en/msg/0ca254effd0acd00 " > Also, I agree this should be in the core of jQuery. I have found the jQuery project to be quite consistent in adding plugins to the core when they are so widely used, that nearly everyone is including them along with jquery.js, so that the addition is natural and welcome. This means lots and lots of people, over a long time, and puts the onus where it should be, on the plugin author. Look at the recent addition of the dimensions plugin (most in v1.2, the rest in v1.2.5). For over a year, this has been one of the most requested plugin additions to the core. So many sites and other plugins use it, it no longer made sense for it to not be in the core. It's a model that keeps the core lean, and gives users as much a vote as to what goes into jQuery as any member of the dev team. Beautiful. " In this specific instance you can either include effects.core.js from jQuery UI, which as Charlie pointed out, contains this feature, or the standalone color plugin: http://plugins.jquery.com/project/color Easy enough for anyone that needs this, and doesn't burden all the people that don't. This is just one example. There are many others, such as: (not exhaustive and in no particular order) * history * cookie * metadata * bgiframe * blockUI - Richard On Fri, Oct 16, 2009 at 2:53 PM, Sam <figaro1...@gmail.com> wrote: > > Well why don't they bundle this in with the jQuery standard library? > > On Oct 16, 11:21 am, Charlie <charlie...@gmail.com> wrote: > > jQueryUi has color animationshttp://jqueryui.com/demos/animate/ > > Sam wrote:I was just wondering, why doesn't jQuery have color animations > built- in to the library?
