What Is a CSS Formatter?

Production CSS gets minified into a single dense line; debugging or modifying it needs indented output. The formatter splits on braces and semicolons, then re-emits each rule with its selector on one line and its declarations indented underneath.

Media queries and other at-rules nest correctly — the formatter increases indentation on `@media`, `@supports`, and `@layer` blocks just like ordinary selectors. Comments are preserved on their own lines so you keep the section dividers and TODOs you (or whoever wrote the file) left behind.

Frequently Asked Questions

What does a CSS formatter do?
It adds indentation, line breaks, and spacing to minified CSS. Each rule and declaration gets proper formatting for readability.
Does it validate CSS?
Formatting focuses on structure, not validation. Invalid CSS may still be formatted. Use a CSS validator separately for syntax checking.
Can it format SCSS or LESS?
Basic formatters work with standard CSS. SCSS and LESS have additional syntax; use language-specific formatters for best results.
