CSS Formatter

Good CSS formatting includes consistent indentation (2 or 4 spaces), one property per line, a space after colons, opening braces on the same line as the selector, and logical grouping of related properties. Consistent formatting makes CSS easier to read, debug, and maintain across a team.

Minifying CSS removes whitespace, comments, and unnecessary characters to reduce file size. This leads to faster page load times, reduced bandwidth usage, and better Core Web Vitals scores. Minified CSS files are typically 20-50% smaller than their formatted counterparts.
