markdown-to-standalone-html/dist/markdown-to-standalone-html.js

Markdown to standalone HTML converter. It generates a standalone HTML with all CSS and images embedded, browsable responsible TOC, math support (KATEX), code syntax highlighting (highlight.js), and rendering of lyrics with chords

Math support is provided with KATEX using standard LaTeX formulae. Surround your LaTeX with a single '$' on each side for inline rendering, or between '$$' for block rendering.

Fenced code blocks are highlighted using [highlight.js](https://highlightjs.org/).

A fenced code block with language 'chordsong' or 'song' can be used to render a song with lyrics and chords using chordsong (https://github.com/juanelas/chordsong). You can alternatively use language 'chords' which will use markdown-it-chords (https://github.com/dnotes/markdown-it-chords) instead.

See example/example.md and its rendered version example/example.html for more help.
