Ticket #7442 (closed bug: patchwelcome)
slideDown/slideUp "jump" when surrounding elements are margin collapsing
|Reported by:||matteosistisette||Owned by:|
Description (last modified by timmywil) (diff)
Whenever you use slideDown("slow") on any object, the animation, instead of being smooth, starts with a little jump. With slideUp, the movement starts smoothly, but it ends with a little jump.
This is not a discontinuity in speed or acceleration, this is a discontinuity in the position, so no matter what the speed curve is supposed to be (accelerating, decelerating, ease in, ease out, no ease, uniform speed, whatever) it is plainly wrong.
I'm testing on Mozilla Firefox, it may work properly in other browsers.
You can try it with any minimal test that uses slideUp and slideDown; see for example http://docs.jquery.com/Tutorials:Live_Examples_of_jQuery and click on the "slide in" and "slide out" buttons in "example B"
