Common mistakes

The input contains invalid or incomplete CSS

Fix: Paste complete CSS rules for the cleanest formatting result.

The user expects linting or validation

Fix: This tool formats CSS, but it does not act as a full CSS linter.

Comments or unusual formatting styles are expected to stay exactly the same

Fix: Beautification normalizes the layout for readability.

The input already contains readable formatting

Fix: The tool may still normalize spacing and indentation into a more consistent layout.

The user expects the tool to fix broken CSS logic

Fix: Beautification improves readability, but it does not repair incorrect CSS behavior.
