I have a fairly long page that leads off with a bold statistic in the hero section of the page. That statistic has an * that needs to be cited where that statistic came from. Should the footnote portion of that come in the same section or at the bottom of the page? Shown below.
There's a third option: a footnote popup.
The physical location of a footnote is in relation to a printed page, in interactive texts, the footnote popup makes much more sense:

The bottom of the page.
