What is CSS Formatter?

CSS Formatter is a tool for converting minified CSS into readable format with indentation and line breaks. Also called CSS Beautifier, CSS Prettifier, or CSS Pretty Print.

Minified CSS saves bytes but is impossible to edit. Formatting splits rules into lines, making style structure clear for work.

Are comments preserved?

Yes. CSS comments (/* */) are preserved during formatting. This is important for keeping documentation in code.

Does it work with @media queries?

Yes. Media queries, @keyframes, @font-face and other at-rules are formatted with proper nesting and indentation.

Is CSS-in-JS supported?

The formatter works with plain CSS. For CSS-in-JS (styled-components, emotion) or CSS Modules, use Prettier in your editor.

Is it safe to paste CSS?

Yes. Formatting is done in the browser. CSS is not sent to the server. You can use it for private projects.

Does it work with SCSS/SASS/Less?

Partially. Basic SCSS may format, but nested selectors and variables may not process correctly. Use specialized tools for SCSS.

Does formatting affect how styles work?

No. Formatting only adds whitespace and line breaks, which browsers ignore. Selectors and properties remain identical.

How to format CSS in editor?

VS Code: Shift+Alt+F or Prettier. WebStorm: Ctrl+Alt+L. Sublime Text: CSS Format. Stylelint with --fix for automatic style fixing.

What property order is best?

Formatter preserves original order. For ordering properties (by type: positioning, box model, typography), use stylelint with order plugin.
