# About

This repository contains code related to docx/epub files conversion to livecarta inner format.

Livecarta book format is tree structure, where nodes are chapters. 
Livecarta chapter is title + html code. Livecarta html code follows some restrictions:

- On structure. It should be not nested, the less nested tags, the better.
  - It is only allowed that the <p> contains <span>, <span> contains <span>.
- The structure tags that are used: `span, p, blockquote, ul, ol, li, table`. 
- List of all valid tags: `iframe, a, span, blockquote, i, s, u, ul, ol, li, strong, p, img, caption, thead, tbody, td, th, tr, table, sup.`
- Styles are added as _inline_, i.e. attribute `style` in html tag.
- Each tag has its own restrictions on attributes and style. See doc/style_config
