and use the `<sup>` tag for the footnote reference, as it has
*meaning* which is important to have proper semantic output (e.g. for
screen readers), as detailed in [this Stack Overflow discussion][].

Note that I also make the bottom `<div>` small as well so that it has
less weight than the rest of the text. -- [[anarcat]]
