DIV/Layer Stay In Place?

hello everyone… :slight_smile: hope you’re all ok.

question:
you know the floating “layers” that are actually <div>'s ?

How on earth do you make those things STAY in place
even if you resize the window ?

i have a flash animation below it that serves as a background for
the DIV in its design and if the div moves a single pixel, it doesn’t
match the background.

i have a 1280x1024 resolution, but people with 1024x768(etc) won’t
see what I see. I don’t even see what’s supposed to see if I don’t
have the IE window Maximized!

Help?

Thanks you guys!
