What Is a CSS Minifier?

A CSS minifier strips comments and every unnecessary space, tab and line break from a stylesheet, producing a smaller file that parses to exactly the same styling rules.

Minifying CSS before deploying it to production reduces the number of bytes a browser needs to download, which can meaningfully speed up page load, especially on large stylesheets.
