Why Format Your CSS?
Minified CSS is great for production, but unreadable during development. Formatting adds consistent indentation and line breaks so you can quickly scan, debug, and maintain your styles.
What formatted CSS means for you
- Easier debugging: Properly indented rules make it obvious which selectors match which properties.
- Consistent style: Enforce the same formatting across your team, regardless of who wrote the code.
- Better diffs: Formatted CSS produces cleaner version-control diffs.
- Smarter reviews: Code reviewers can focus on logic, not formatting inconsistencies.
Safe formatting
Toolza never changes the meaning of your CSS — only whitespace is adjusted. Strings inside quotes and url() calls are preserved exactly as written.
