FAQs

What does this tool do? ▶

This tool helps clean up your CSS by identifying and removing duplicate property declarations within the same CSS rule. It keeps the last declared value for any duplicated property, following CSS's cascade rules.

Why should I remove duplicate CSS properties? ▶

Removing duplicate properties can make your CSS more readable, easier to maintain, and slightly reduce file size. While browsers inherently handle duplicates (by applying the last one), explicitly cleaning them can prevent confusion and potential unintended overrides.

Does this tool minify CSS? ▶

No, this tool primarily focuses on removing duplicate property declarations. It does not perform minification (e.g., removing whitespace, shortening names, or combining rules).

What about comments in the CSS? ▶

The tool attempts to preserve comments associated with selectors and properties. However, for duplicated properties, comments for the overridden declarations will not be included in the cleaned output, only the comment for the kept property.
