Occasional TOC navigation issues (epub goes to wrong loc'n)

[therealjoeblow]

I usually convert my source files, whether they are original .epub or .mobi to .htmlz so I can edit them for my preferences in styling, font sizes, etc., and then convert .htmlz back to .epub for use on my kobo.

In 99% of cases everything works perfectly.

However in a small number of cases, TOC navigation gets screwed up in a very minor way in the final epub - ie, selecting a TOC entry navigates to the last line of the text page *before* the actual chapter, instead of to the top of the page where the chapter number is as would be expected. When using the TOC on the original epub, it doesn't do that, and when using the in-line TOC in the HTML file it navigates exactly to the chapter number text, but not in the .epub.

Anyone know why and if there is a simple fix?

I think this has to do with where the Anchor was placed in the original file Before a split happens in Calibre.

I am not sure that Calibre can detect an Anchor that happens Before an Chapter heading.

Yep, I had an anchor, then the <div class="pagebreak"> then another anchor, then my chapter heading (h2). I moved the pagebreak to before the first anchor (so now I have div, a, a, h2) and it works fine, only this is a manual pain in the butt. I was hoping there was some way to tell Calibre to put these in the right order, regardless of how the original source put them, but I guess that's asking a bit much...

If you have a Chapter per file, there really is no need for a chapter anchor.
(the #...) part in the NCX. the chapter_filename is enough. The file opens at the beginning in lieu of any directive.

You do need mid file anchors., but those are not the problem you are having.

You don't need anything other than the chapter heading tags (<h2> in your case) in your html file. Calibre will insert the chapter pagebreaks when you convert the html to epub, depending on your settings on the Convert - StructureDetection page.

True, but without the anchors, then the in-line TOC (ie with the HTML hyperlinks) doesn't work...

You don't need anchors in the Chapter files.

Sample TOC:

BTW I had to fix the file nameD, they were off by one. Chapter 1 was calling the Prologue file (someone else's Calibre conversion)
