Format and beautify CSS online. Expand minified CSS into a clean, indented form in your browser.
About CSS Formatting
Production CSS is usually minified — every byte saved is worth saving when stylesheets ship over the wire on every page load. But minified CSS is tedious to read, debug, or compare. The CSS Formatter expands minified CSS into a clean, indented version with one declaration per line, blank lines between rules, and consistent spacing.
How to use
Paste your CSS and press Format for the readable version, or Minify to strip whitespace and comments down to the smallest valid form. Comments are preserved by the formatter and removed by the minifier. The tool changes only whitespace; selector specificity, declaration order, and behavior are untouched.
