使い方
使い方
- Paste CSS up to 200,000 characters into the editor.
- Choose pretty or minified output and an indentation width.
- Format the stylesheet, review any syntax warning, then copy or download the result.
Readable CSS output
Pretty mode places selectors, declarations, at-rules, and closing braces on separate lines with your selected 2–8 space indentation. Minified mode removes unnecessary whitespace while keeping strings and comments intact.
Local processing with clear limits
Your stylesheet stays in the browser. The formatter reads up to 200,000 characters and reports unbalanced braces, parentheses, brackets, or unterminated strings before producing output.
よくある質問
あわせて知りたいこと
Does this upload my CSS?
No. Formatting, copying, and downloading happen locally in your browser.
Does the formatter change CSS values?
No. It changes whitespace around structural punctuation and preserves declaration values, comments, quoted strings, and functions.
Can I format SCSS or Less?
The tool is intended for standard CSS syntax. It preserves many custom property values and at-rule blocks, but it does not compile preprocessors.
What happens when CSS is incomplete?
Formatting stops with a clear warning when braces, brackets, parentheses, or quoted strings are unbalanced.
