## What it is
A CSS stylesheet that replicates GitHub's Markdown rendering style with minimal code. It provides seven themes including automatic light/dark switching and colorblind-friendly variants.

## Use cases
- style rendered markdown to look like github
- add github-style css to my blog
- render markdown files with github styling in a web page
- dark mode markdown stylesheet
- make my documentation look like github readme

## When to choose
- you want your rendered Markdown to look exactly like GitHub's
- you need light/dark theme support out of the box
- you want a lightweight, drop-in CSS file with no JavaScript

## When to avoid
- you need a full Markdown editor or parser (this is styling only)
- you want a customizable design system rather than GitHub's fixed look
- you need styling for non-Markdown HTML content

## Facets
- artifact type: library
- maturity: stable
- function: css-framework, ui-components, markdown
- domain: web-development, frontend, documentation
- platform: browser
- tags: markdown-styling, github-style, dark-mode, themes, css, web-server, nodejs
