Footer issues-background image doesnt extend entire page when minimized

I am quite new to css and have stumbled my way through making a page. My issue is the footer. My footer contains a background image that repeats across the page. In order to make the footer stick to the bottom I have placed it in a container. My issue is, when the page is minimized and you scroll over the right of the page, the menu that is on the bottom is on the right but the background image does not extend behind it.

Here is a link to my site. Minimize the page and scroll all the way to the bottom right to see the issue. Please let me know if you need anything else.

Any help would be appreciated!
