CrossSlide. CrossSlide is a jQuery plugin implementing in 2kB 1 of Javascript code some common slide-show animations, traditionally only available via Adobe Flash™ or other proprietary plugins. CrossSlide builds upon jQuery's animation facility, so it is as portable across browsers as jQuery itself (that is, a lot!) Internally CrossSlide does not rely on lookup tables, building instead a "chain" of functions. Each function starts a linear phase of the animation through jQuery, setting the next function in the chain as a complete callback.
