I am looking for a theme whose content region automatically expands to fill the sidebar regions when those shrink. ie the content region and sidebars must be in the same container with the content region designed to expand to fill the sidebar regions when those shrink. It is mainly to free the space taken up by the elements and menu in the sidebar when during editing content I don't need them, but call them out when I do. It should be a theme without wasted space and designed to use all the screen area. I want to use the JQuery slide toggle system to expand the side bars when I need them,and shrink them when I don't.
e.g. I currently have Admin doing something similar but it shifts the whole page and has its own menu style. I want the header and footer areas intact and just the content area expanded and contracted as required.
I just want to load up Firebug and adjust the sidebar widths and if the content region expands or contracts to fill the space or shrinks I'll be happy to apply my JQuery.
