sindresorhus/github-markdown-css

This is a CSS stylesheet that makes text rendered from Markdown look exactly like it does on GitHub. Markdown is a lightweight way to write formatted text using plain characters, and GitHub converts it into HTML when displaying README files, comments, and documentation. This project captures the visual styling GitHub applies to that HTML so you can replicate it on your own website or application. Using it is straightforward: you include the CSS file in your page, wrap your rendered Markdown content in an element with the class markdown-body, and the styling takes over. The package includes seven theme variants covering light mode, dark mode, high contrast, and colorblind-friendly options. The default stylesheet automatically switches between light and dark based on the visitor's operating system preference. The CSS in this repository is generated automatically from a companion tool rather than written by hand. If you want to contribute changes or generate a custom version, the README points to the generator repository. This is a frontend utility for developers building tools that display Markdown content and want it to look familiar to GitHub users.
