CSS Floats, Inlines and Centering

This problem is driving me nuts.

I want to make a yellow box with a red border. (Must be two divs).  I want to be able to move the yellow box and change its size and still have the red border hug it tight.

I asked Experts-Exchange and got no love.  I joined the CSS-d mailing list, but my post never made it.  I can’t believe this might not be possible in either browser.


Whatya think?
