navmainwrapper and navsupwrapper!

[usernamenone]

I am trying to move my code for my navmainwrapper and navsupwrapper so those 2 are at 100% of the screen and the rest of the page is left at the standard 750px;

I know both codes are in the header and footer but I am only able to destroy the page!

Any help would be appreciated.

Those div's are contained within the mainWrapper and or the centercontent area...so if the main is set to 750px or the center is 750 minus the sidecoxes this is what you have to work with. If you want this for looks check the source for the home(Zen Cart) page here for how the top banner is constructed.
