animate relative div understanding problem

animate relative div understanding problem

Hi all,

I posted this question in another place but didn’t get any answers, so I will try again in a little more abstract way.

I am having trouble in understanding a principle thing.

Is it possible to animate (=move) a div that is relative - but so that the attached divs that lay in the flow of the page behind it change their position, too? 
I am having big troubles to make this come true properly.

To explain: no problem to put other divs INSIDE the animated div and make them so move parallel to the parent.
But I need them OUTSIDE the div but still want that it moves in the same way without extra selecting it and animating it, too.

Do I explain what I mean?

Thanks for help, ideas, demonstrations!!
