The W3C CSS3/SVG Validator bookmarklet opens the W3C CSS Validation Service in a new window to validate the page's CSS against CSS3 and SVG specifications. Passes the current page URL to jigsaw.w3.org/css-validator with the css3svg profile and warnings disabled. Useful for identifying modern CSS issues and SVG styling problems. Requires the page to be publicly accessible or same-origin for the validator to fetch stylesheets.
