similar to this site.(huge mod)

[forcer]

i am trying to get my forum similar to how this site is laid out.

the way i see it is that there is a table(outer table) and then the forum and content table edges seem to be slightly in about 1cm (inner table) and then the gap between each forum section.

am i right in what i am saying? if so hows it done?

i then want to go onto adding a background wallpaper to the outsides of the table and then adding all my graphics, so basically similar to this sites kinda layout, but not exactly.!

any help appreciated
