Description from store
It extracts only the CSS used by the current page and uses the service provided by W3C to validate the CSS.
How it works:
- Activate the extension on the desired browser page
- The extension extracts only the CSS used by the current page and copies it into "Validate by direct input" of the CSS Validation Service (https://jigsaw.w3.org/css-validator/#validate_by_input).
- By pressing the "Check" button, the W3C service checks that CSS style validity
This way you can select only the CCS you really need and check the CSS compliance with W3C standards.
