Moving the sidebar below the content

Our next layout challenge is to make the content and the sidebar easier to read by placing them one above the other instead of side by side. This is particularly important for phones in portrait mode, on which the two elements are both far too narrow to read and look decidedly odd. It's also helpful on phones in landscape mode, which still have quite a narrow window. For iPads in landscape mode it really isn't necessary, but for the Carborelli's site we will also amend the layout for iPads and other tablets in portrait mode, just to make better use of the screen.
