		Font sizing, using relative font size elements borrowed from LaTeX. Note that we use CSS relative font sizes (smaller and larger), which means that we have to string a bunch of them together to achieve the same effect as a single command in LaTeX. We can't use absolute sizes in CSS as they would probably look different on different machines.
