Can we use non-TOC headings, such as Heading 4 or 5?
I've read everything I can find in these wonderful guides and posts, but I can't find an answer to this basic question:
May I use additional headings, such as Heading 4 or 5, to format text without creating TOC listings and without messing up Epub conversion?
(This question assumes the additional headings won't be exotic, involving Wingdings etc., but just slight variations on style.)
All the info I see makes clear that the Epub conversion process will only recognize Heading 1 (Title), Heading 2 (typically, Chapter) and Heading 3 (typically, Section of a Chapter) for compiling a Table of Contents.
Normal (text body) is ignored for TOC compilation, and the conversion process accepts variations on Normal, such as italics and bold.
However, when I look at many nicely laid-out ebooks, I see styles that are not 1,2,3 or Normal.
I see them most often on title pages, where subtitles, author's names and/or publisher's names are shown in sizes or even fonts not consistent with 1/2/3/Normal.
The advantage in being able to use a "Heading 4" (subtitle?) and "Heading 5" (author's name) would be
1) better look on title page, and
2) acheiving emphasis for this info without triggering a TOC listing. (E.g., if author's name is in Heading 1 or 2 so as not to look too small on title page, author's name becomes a TOC item, right?)
Please excuse me if there are functions I do not understand (e.g., does the Epub converter automatically exclude book's first line, the title, from TOC? Does it automatically do something special with subtitle, author's name or other title-page formatting?) But I'd be grateful for any such information, as well as an answer to my basic question: May I use additional headings, such as Heading 4 or 5, to format text without creating TOC listings and without messing up Epub conversion?
