}What this formatter does
Rearranges CSS-like text with line breaks after opening braces, closing braces, and semicolons, plus two-space indentation inside brace levels. It provides a quick readable view and a copy control for the output.
How to use it
Paste CSS into the editor and the formatted result updates immediately. Copy the result when ready, or use Reset to clear the editor; Reset does not restore the original sample.
Formatting behavior
Outside quoted strings and comments, runs of whitespace are reduced and declarations are split after semicolons. Quoted content, escaped characters, block comments, and recognized // line comments are preserved while braces change the indentation depth.
Important parser limitation
This is a lightweight character-based formatter, not a CSS parser, validator, linter, or standards compliance check. It does not normalize spacing around colons, sort properties, expand shorthand, add missing punctuation, or report unmatched braces and invalid declarations.
Safe review workflow
Formatting is intended to change presentation, but malformed input, unusual escapes, data URLs, custom syntax, or nonstandard comments may produce surprising layout. Review and test the copied stylesheet before production use; keep the original source available.
Privacy
Processing happens locally in your browser. The pasted CSS is not uploaded by this tool.
