GitBook generates epub with duplicate headings

Bobík · 02-28-2018, 07:16 AM

I have ebook in markdown files and use GitBook for generating epub file. Like usual, chapters are defined in SUMMARY.md and chapter files begins with a headings (the same like in summary):

Code:

Title of the chapter
====================

GitBook uses Calibre's tool ebook-convert to generate epub files what will have html files with title section like:

Code:

  <body class="calibre">

<div class="page">

        <h1 class="book-chapter2" id="calibre_toc_2">Title of the chapter</h1>
        <div class="section">
            <h1 id="příběh-první" class="calibre17">Title of the chapter</h1>

First h1 have display: none; in CSS, so will not be visible in most readers, but some of them ignores it and renders heading twice.

Is there a way hot to configure GitBook or epub-convert to not add second heading and keep table of contents working?

calibre does not duplicate headings, you will need to ask the developers of gitbook.

I don't use Gitbook, but I would just remove all the first lines for each of the chapter titles. You only need to list it once per chapter.
