Main change is replacing a whole lot fewer manual pixel offsets with a
few divs.

Also, less over-specification of font stuff. Most of it is applied
page-wide; we don't need to constantly re-declare that we are using
nunito :)

This is a somewhat "sloppier" implementation than previous pages; it is
not a pixel-perfect recreation of the previous state, which takes way
too much time; it's easier to do this and ask what tweaks are needed.
Also, this one was particularly difficult to figure out what values the
margins would actually have needed to be.
