Keeps or strips CSS comments based on your preference.
Syntax Highlighting

FAQ
Why format CSS code?▾
Formatted CSS is easier to read, debug, and maintain. Minified CSS loads faster in production but is hard to edit directly.
Does the formatter support SCSS or LESS?▾
This tool focuses on standard CSS. SCSS and LESS have their own preprocessors and dedicated formatters for their extended syntax.
Will formatting change how my CSS behaves?▾
No. Formatting only changes whitespace and line breaks — it does not alter the logic or specificity of your CSS rules.
Can I format a full stylesheet?▾
Yes, paste any length of CSS. The formatter handles large stylesheets including framework CSS like Bootstrap or Tailwind.
CSS Best Practices for Developers
- Keep CSS declarations in a consistent order (e.g., alphabetical or by box-model category) across your team.
- Use a CSS linter (Stylelint) in your CI pipeline to enforce formatting rules automatically.
- Minify CSS for production builds — tools like cssnano integrate with Webpack and Vite.
- Avoid inline styles in HTML — keep all CSS in external stylesheets for maintainability.
- Use CSS custom properties for theme values to make global changes in one place.
