When to use this CSS beautifier
Use this CSS beautifier for selectors, declarations, media-query snippets, and copied style blocks that need clearer spacing before editing. Clean formatting makes it easier to spot duplicate properties, missing semicolons, and rules that should be grouped together. The goal is not only to make the content look cleaner, but to make parent blocks, nested values, and repeated sections easier to inspect before you save or share the result.
Beautifying content is especially helpful before running a comparison. When indentation and line breaks are consistent, real changes are easier to find and formatting noise is less distracting.
