What is CSS Minification?

CSS minification is the process of removing all unnecessary characters from CSS code without changing its functionality. This includes whitespace, newlines, comments, and redundant semicolons. The result is a smaller file that loads faster in browsers.

Why Minify CSS?

Every byte saved reduces page load time. Smaller CSS files mean faster parsing, faster rendering, and better Core Web Vitals scores — which directly impact SEO rankings and user experience.
