What is CSS Minification? âš¡
CSS minification is the process of removing unnecessary characters from CSS code without changing its functionality. This includes removing whitespace, comments, unnecessary semicolons, and optimizing values to reduce file size.
Minified CSS loads faster, uses less bandwidth, and improves website performance. It's an essential optimization technique for production websites, especially for mobile users and slower internet connections.
