W3C CSS Validation

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.
