What is Validity?

"Validity" is a handy Chrome extension that allows users to quickly validate HTML documents directly from the toolbar. By simply clicking the icon, users can validate the current document without navigating away from their page. It displays the number of validation errors in the toolbar and detailed results in the Chrome's developer tools console. Additionally, Validity provides the option for users to leverage their own installation of the W3C Validation Service for further customization and control.
