W3C CSS Validator for the current browser page
Allows you to validate the CSS of a .css page using the service provided by the W3C.
How it works:
- Activate the extension on the desired browser page (it must be a page containing only CSS)
- The extension extracts the content of 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 check the compliance of the CSS with the W3C standards.
