 Hi Adentone,

It looks like the combined width of your li's are wider than its container on the moment of the beginning of the animation,

This forces the right  floated element to the bottom and this triggers the vertical scrollbar in many cases becasue the page is extended by the height of the li.

The scrollbar is the "jump" you see because this makes all your content shift 10 pixels to the left becasue of the vertical scrollbar taking up about 20px (depending on OS and settings).

 So, I added to the accordion class   height: 400px;  overflow: hidden;  and that seemed to stop almost all of the "jump".

Now, do you have any further suggestions on how to make the animation more smooth?  Specifically, the right edge of the accordion seems to "vibrate" during the animation...  any ideas to keep that more steady?
