Помогите изменить расположение сайдбара

Добрый день.
Столкнулся с такой проблемой. Нужно изменить расположение сайдбара.
Вот, сайт Ссылка

CSS файл — screen.css

За расположение сайдбара отвечают .div span-7, .div span-4 .last

Но что-то не получается изменить расположение сайдбара функцией float

Также как изменить расположение «фона» сайдбара?
