I don't know how to do that.  An additional constraint is that, at least
for the default output, it should look ok with no CSS, so if an header
pops up when there is no CSS this is not good.

If somebody knows the HTML that allows to do it I could add it.

It would also be nice to implement correctly in LaTeX output.
Currently, for the LaTeX output, the prototype is converted to plain
text and used to compute the fractions, which is bad (maybe doing
nothing would be better actually), but if it is doable in Texinfo TeX
(and it seems to be done with a little bit of code) it should be doable
in LaTeX too.
