Спасибо rus, но я немного другое имела ввиду. Футер расположен 'ниже' чем нижняя граница окна браузера, и при прокручивании странички вниз блок меню как-бы'пустой', то есть растянут только на высоту окна браузера. Надо чтобы он при прокручивании вниз растягивался тоже (если это возможно). Вот ваш же пример с моими дополнениями: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <html> <head> <meta http-equiv="Content-Type" content="text/html;
