It seems to be that the visual continuous media equivalent of a footnote
is something like a tooltip or pop-up box containing some text. It'd
only be displayed when the user requests it, by clicking on or hovering
over it. Paper documents permanently display the footnotes only because
of the limitations of the media.
Doing click-to-view "footnotes" with current CSS is tricky, but doing
hover-to-view is reasonably straightforward using some trickery with the
:hover pseudo-class and display:none, as long as the footnote content is
Reverting to traditional footnotes for print media based on the same
markup is not straightforward, however. The CSS3 support for shuffling
elements about would do it, but we're not there yet.
