Primer CSS Markdown

Last Updated : 28 May, 2025

Primer CSS is a free open-source CSS framework built with the GitHub design system to support the broad spectrum of Github websites. It creates the foundation of the basic style elements such as spacing, typography, and color. This systematic method makes sure that our patterns are steady and interoperable with every other. Its approach to CSS is influenced by object-oriented CSS principles, functional CSS, and BEM architecture. It is a highly reusable model.

Markdown is a lightweight markup language for creating formatted text. In this article, we will learn about the markdown with Primer CSS.
