Runtime-first · No build step
Docs and blog, straight from Markdown
Write .md, generate a manifest.json, and the browser renders the whole site — themeable, accessible and tiny.
Just Markdown
Front matter, footnotes, callouts and built-in syntax highlighting. Raw HTML is escaped by default.
Themeable by tokens
One stylesheet of --md-book-* custom properties. Light and dark ship in the box.
Blog included
Date-sorted posts, tags, categories, pagination and RSS / Atom / JSON feeds.
Vertical writing
Set tanka and other Japanese text in 縦書き, with ruby and a :::tanka block.
Accessible
Skip link, landmarks, focus rings, reduced-motion support and a keyboard-friendly drawer.
This example site is the fixture used by md-book’s own dev server and tests.
