HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as pseudo-element.
The ::file-selector-button has not been recognized by the W3C Validator. This seems to be a bug in the W3C Validator, which has already been reported.
The ::ng-deep CSS selector is often used in an Angular Component’s CSS to override the styles of a third-party component or a child component’s styles.
This CSS selector is now deprecated.
