Useful article on relative and absolute positioning with CSS2 here.

I’m still looking for a solution to floating the text and client news box divs on my index page which allows me to specify a fixed width for the box and no width for the text so it expands to fit which will work in both IE and Firefox. Thus, at present I have gravitated to absolute positioning of the divs which has a disadvantage in that if the news box becomes too long it obscures the footer div.
