Hi
I'm trying to design a simple three-column website using html and an external stylesheet.
I have a header of 750px wide, navbar underneath is the same width, both centred.
Now I want to put three columns underneath (left and right 150px wide; middle to fit the remaining space), lined up with the left and right edges of the header/navbar. At the bottom, I want to add a footer right across to match the navbar.
I've just realised that I can't easily position the left and right columns on the page because I don't know how big the viewer's screen will be, so can't say what margin size should be.
There must be a way of lining everything up.
Any advice?
Ta.
