What is CSS minification?

Removing unnecessary characters (whitespace, comments) without changing functionality, reducing file size.

How much size reduction?

Typically 20-40%. Combined with gzip, total savings can be 70-80%.

Should I minify for production?

Yes. Minified CSS loads faster. Most build tools can minify automatically.

How much file size reduction does CSS minification typically achieve?

CSS minification typically reduces file size by 15-30%. Combined with gzip compression, total savings reach 70-85%. The exact reduction depends on how many comments and whitespace the original file contains.

Can I undo CSS minification to get the original formatting back?

You can beautify (unminify) CSS to restore readable formatting with proper indentation, but original comments and specific whitespace style will be lost. Always keep your source files separate from minified output.
