A PostCSS plugin that automatically adds vendor prefixes to CSS rules using data from Can I Use.
Autoprefixer is a PostCSS plugin that automatically adds vendor prefixes to CSS rules using data from Can I Use. It solves the problem of writing cross-browser compatible CSS by handling prefixing based on real-world browser support, allowing developers to write clean, future-proof CSS without manual prefix management.
Frontend developers and teams using modern CSS who need to ensure compatibility across different browsers, especially those integrating PostCSS into their build pipelines.
Developers choose Autoprefixer because it automates a tedious and error-prone task, reduces CSS bloat by adding only necessary prefixes, and integrates seamlessly with popular build tools and workflows. Its data-driven approach ensures prefixes are always up-to-date with browser trends.

Adds necessary vendor prefixes automatically using real-time data from Can I Use, eliminating manual work and reducing errors.
Integrates with Browserslist for customizable browser support via config files, ensuring consistency across build tools.
Provides optional prefixes for CSS Grid in IE 10-11, including limited autoplacement, easing legacy browser support.
Works with various build tools like Webpack and Gulp, plus CSS-in-JS via PostCSS, fitting easily into existing workflows.
Grid autoplacement for IE has significant restrictions, such as no support for auto-fit/auto-fill and issues with manual placement, requiring careful testing.
Only handles vendor prefixes, not polyfills for new CSS features, so additional tools are needed for full cross-browser compatibility.
Enabling Grid prefixes requires specific options or environment variables, and can break existing layouts if not handled cautiously, as noted in the warnings.
