## What it is
A demonstration repository showing how to style GitHub README files using CSS embedded in SVG images. It serves as a visual example and explanation of a trick for adding custom styles to markdown documentation on GitHub.

## Use cases
- style my github readme with custom css
- make readme headers animated or styled
- learn how css works inside github markdown
- customize readme appearance beyond markdown
- embed styled svg in a github readme

## When to choose
- you want custom visual styling in a GitHub README
- you want to learn the SVG-in-markdown CSS trick
- you need an example to copy for styled readme headers

## When to avoid
- you need a general CSS framework for a website
- you target platforms that sanitize SVG styles other than GitHub
- you want a maintained library with an API rather than a demo

## Facets
- artifact type: learning-resource
- maturity: stable
- function: css-framework, markdown, documentation
- domain: documentation, web-development, developer-tools
- platform: browser
- tags: github-readme, css-trick, svg-styling, readme-customization, demo, web-server
