Frequently Asked Questions

What does the CSS formatter do?▾
The CSS formatter parses your CSS code and outputs it with consistent indentation, one property per line, and proper spacing around selectors and values — making your stylesheets easy to read and maintain.
Does it support modern CSS features?▾
Yes. The formatter handles CSS custom properties (variables), nested rules, media queries, @layer, @container, and other modern CSS features supported by Prettier's CSS parser.
Can I format SCSS or LESS?▾
This tool is designed for standard CSS. For SCSS or LESS preprocessing languages, the output may not be perfectly formatted. Consider using dedicated SCSS/LESS formatters for those languages.
