Stylis is a lightweight, fast, and modular CSS preprocessor. It parses CSS-like syntax and transforms it according to defined rules. Key features include vendor prefixing, nesting support, and CSS minification capabilities. Its speed and small footprint make it suitable for performance-sensitive environments. It can be used in Node.js, browsers, and other environments.
Stylis npm package downloads show a strong upward trend from March 2024 to July 2025, reaching over 90 million. After a small retraction in August, September 2025, the current month, shows significantly lower downloads so far, being incomplete.
