How to Write Notes in HTML for Calibre to Recognize as Pop-Up Note in EPUB Conversion

zevi svei · 01-18-2025, 10:05 PM

I'm looking for the best way to format comments or annotations in an HTML file so that they appear as pop-up notes in an EPUB after converting the file using Calibre.

I want the annotations to behave like endnotes or footnotes that users can click or tap on to view as a pop-up within the text.

I'm not sure if there is a specific HTML structure or class that Calibre recognizes for this purpose during conversion.
