With the extension installed, you’ll see a small icon saying ‘HTML’ in the address bar for every HTML document loaded that supports a validation check.
Click this icon or press Ctrl+Alt+V to run the validation check. The extension will contact a W3C validation service and find out errors (if any) in your HTML document. The good thing about Validity is that it also allows you to your own installation of any validation service.
Validity can come in handy to perform HTML validation tasks without going through much hassle, especially if you’re a fan of Google Chrome. Let us know what you think.
