I'm not sure where to post this question. But, since I was in the Calibre Editor when I messed things up, I figured this forum might be acceptable.

Anyway, I managed to destroy the footnote links in an epub and thought it wouldn't be a problem to re-create them. Unfortunately, I can't seem to figure it out. From what I can see, roughly speaking, the book puts the footnote text down at the bottom of the chapter/file, prefaces it with a paragraph id and a link back to the place in the text where it's called. With most of the extraneous stuff stripped out, that footnote text looks like:

Code:

<p id="footnoteid"><a href="#returnfootnoteid"><sup>*</sup></a>the note</p>

Up in the text, the call to the footnote is simply a link to the spot:

Code:

<a id="returnfootnoteid" href="footnoteid"><sup>*</sup></a>

But, when I look at W3C's information on footnotes, I find:

https://www.w3.org/MarkUp/html3/footnotes.html

which uses an <fn> element to do the same thing and doesn't have a return function. The equivalent of the above is:

Code:

<fn id="footnoteid"><sup>*</sup>the note</fn>

and

Code:

<a href="#footnoteid"><sup>*</sup></a>

Of course, I've found other ways to do the same thing:

https://stackoverflow.com/questions/...otnote-in-html

And some references to even more ways that seem to require epub3 which I can't even understand:

https://github.com/kobolabs/epub-spe...kobo-platforms

and

https://www.w3.org/publishing/epub3/...type-attribute

But, for Calibre and my Kobo Forma, what would be the best way to do footnotes? Note that the footnote behavior is different in Calibre's Viewer between the <fn> element version and the supposed original way the book did it (the <fn> "window" seems to show the whole screen from the footnote text up, while the "original" way seems to just show the footnote text.
