How do I make footnotes work with the standard reader software? I have a book with a footnote reference:
Code:
<p>Text text text <a href="#fn1t" id="fn1s" role="doc-noteref" epub:type="noteref">[1]</a>
and the footnote:
Code:
<aside id="fn1t" role="doc-footnote" epub:type="footnote">
<p><a href="#fn1s">[1] Footnote text</a></p>
</aside>
but this fails to work - the footnote does not display in a popup, nor does it take me to the actual footnote at the bottom of the file. Short tapping on the [1] just brings out the UI, while long pressing just shows the highlight dialog - it doesn't seem to react at all to the link. OTOH, tapping the back-link in the footnote does work, so maybe I'm just hitting the sweet spot?
This book validates in EbookCheck 5.0 as Epub3.3. and the footnote works both in Calibre's viewer (pop-up) as well as in KOReader (real footnote at bottom of screen) and to varying degrees in several other readers as well. I read the specs on Github and it looks like Kobo has some special way of showing footnotes, but is the footnote support in vanilla software really this rudimentary? Since this is just my own modifications to a PG book, I'm not terribly concerned with it and will probably just continue using KOReader, but it bothers me why the standard viewer cannot a display fully validating ebook properly.
