Open the epub in Sigil or calibre's editor and look for code similar to:
Code:
<a href="#footnote1" epub:type="noteref" >1</a>
and
Code:
<aside id="footnote1" epub:type="footnote" >
Footnote text
</aside>
and in the header for the epub file look for the <html> tag where you should see xmlns:epub="http://www.idpf.org/2007/ops"
Code:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops" >
You may want to check such site as the Daisy kb for items like Notes for more information including adding a return link.
And please note that nothing in the epub3 specs requires footnotes to be popups. I have looked through those specs several times and it appears that how to display footnotes is left as an exercise to the programmers of the rendering engine. |
What is the correct way to do footnotes that works in epub 2 & as a popup in epub 3 on a Kobo? <aside> is not ePub 2 compatible and will not work if used in an ePub 2 viewer.
