float elements left without wrapping

Hello all,

A bit new to CSS layouts - I've been putting everything in tables until
now. I'd like to line up several divs all floating left, so they stack
up across the screen. But I don't want them to wrap when they hit the
edge of the screen, ie. a horizontal scroll bar will appear. A weird
requirement I know (it'd take a LOOONG time to explain why). I can see
how I could do this with absolute positioning - but that's something I
really want to avoid..

I'd really appreciate any help!
Thanks,
Russ
