Is possible to add footnotes?

[fargo]

oeb-page-foot is good for footers, but for footnotes, I'm not sure. To see what I mean, consider the situation when there are two or more footnotes references[1] being simultaneously displayed on the same screen[2]. How a reader should deal with them?

it won't - unless you 'fix' the length of page yourself ....

Well then you would create one footer with both footnotes, and put it above the first reference. You would clear it after the second reference. That way the footer would be in effect while either of the two references are visible, and disappear after they are gone.

That only works for footnotes that are very short. Otherwise the footer line becomes a paragraph and doesn't fit on the page any longer.

Personally I think a footnote should be done as <ref>This is a footnote</ref> and let the rendering program do it however it wishes. For example you might select the footnote and the program could pop up a window to display it in.

Actually that's exactly what the spec says, Reading Systems can choose how they will display footers and headers. It even mentions the possibility of popping these up separately.

The concept of having footnotes at the bottom of the page is an artifact of printed books. There's no reason why we can't have them as pop-ups. The content producer should be able to add an "display: oeb-page-foot" element describing the reference content above the first reference and have the Reading System take care of the details.

And all this is entirely supported by the spec:

All I'm saying is that you could easily achieve "footnotes" with epub footers.

do ePub current devices support 'pop-ups' ?

Not a single one.

Then again, ADE and the like have a ways to go to supporting the epub spec in many other areas too, not just headers and footers.
