What CSS formatting does
CSS formatting adds consistent indentation, line breaks, and spacing around selectors and properties — making stylesheets readable for humans. Minification strips all whitespace for smaller file sizes in production.
How to use
- Paste your CSS into the input.
- Click Format / Beautify to pretty-print, or Minify to compress.
- Copy the result to your clipboard.
Your CSS stays in your browser — no data is sent to any server.
Frequently Asked Questions
- Does it handle CSS variables and modern syntax?
- Yes. The formatter handles CSS custom properties, calc(), clamp(), nested selectors, and @media/@keyframes rules.
- Is minified CSS valid?
- Yes. Minification only removes whitespace that has no semantic meaning in CSS.
