Added a background colour to the container

Added a background colour of #FFFFEE to the container.
Added 20px padding to content container

Added 20px padding to content container. Decided this looked better than
adding 20px of margin (as that affected the page centering).
Added a box shadow to the content container

Added a box shadow to the content container, with a offset of 6px on
both the x and y, and a blur of 5px. Added the -moz and -webkit versions
as well.
Added a border to the content container

Added a solid border, with 1px width and the colour #CCCC00, to the
content container.
Added a gutter between the main text and the sidebar

Added 15px of padding to the left hand side of the sidebar so that a
gutter is created.
Changed the font of the entire page to Arial

Changed the font of the content container to Arial (the container wraps
everything in the body, so changing the property there affects
everything).
Converted site to use bootstrap
