I compared the original ebook with one converted to EPUB 3 in Calibre. The original (EPUB 2 btw) is showing footnotes at the bottom of the page, but EPUB 3 is not. Footnote reference in text is the same across the two:
Code:
<a id="footnote-225-backlink" class="footnote" href="naglowki_001_0014.xhtml#footnote-225">2</a>
They differ in the code on the actual footnote:
Original
Code:
<div class="footnote">
<p><a id="footnote-225" href="naglowki_001.xhtml#footnote-225-backlink">2</a> Sun Tzu, Sun Pin, Sztuka wojny, tłum. Dariusz Bakalarz, Gliwice 2021, s. 26.</p>
Converted epub
Code:
<div class="footnote1">
<p class="calibre9"><a id="footnote-225" href="naglowki_001.xhtml#footnote-225-backlink" class="calibre14">2</a> Sun Tzu, Sun Pin, Sztuka wojny, tłum. Dariusz Bakalarz, Gliwice 2021, s. 26.</p>
Is there a way to maintain on-page footnotes with Calibre conversion?
