Creating new themes

[Gazook89]

Wanted to create a spot to drop tidbits about creating new themes, either "official/baked in" or "user themes".

Special HTML classes

Header Navigation

The Header Navigation panel in the Preview pane generates it's table of contents by pulling \page numbers, but also factors in pages with the selectors .frontCover / .partCover / .backCover / .insideCover / .toc. It takes these pages and pulls some text from them, if available, to generate special listings in the Header Nav that look like this:

Specifically, if a page has one of those classes in it, it will pull the first H1 header text out as the label for that list item.

So new themes might benefit from keeping these class names handy in their snippets. Relevant file is headerNav.jsx
