CSS files are render-blocking resources, meaning the browser must download and parse them before it can display your page. The larger your CSS files, the longer users wait to see content. CSS minification reduces file size by removing all unnecessary characters without changing the stylesheet's behavior.
Minification removes whitespace, newlines, comments, and shortens property values where possible. For production websites, minified CSS is an industry best practice recommended by Google PageSpeed Insights, GTmetrix, and every major web performance tool.
Smaller CSS files mean faster render times and better user experience.
