Why minify CSS?
Minified CSS loads faster because it removes unnecessary characters like whitespace, comments, and newlines. Smaller files mean faster page loads and better Core Web Vitals scores. Always minify CSS for production.
Frequently Asked Questions
What does CSS minification remove?
Minification removes comments, whitespace, newlines, and redundant characters. It may also shorten color values and remove the last semicolon in rule blocks.
How much can I save by minifying?
Typical savings are 20-50% depending on how formatted your CSS is. More comments and whitespace means more savings.
Will minified CSS work the same?
Yes, minified CSS is functionally identical. Only formatting is changed - the styles render exactly the same.
Should I minify during development?
No, keep CSS readable during development. Minify only for production builds. Most build tools handle this automatically.
What is CSS beautification?
Beautification is the opposite of minification - it adds indentation and line breaks to make compressed CSS readable again.
