HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as touchstart.
The ontouchstart attribute, used in devices with a touch screen, and not supported by all browsers, is not a valid attribute in the current HTML5 standard.
You can consider replacing it with the more generic onclick attribute, or still use it if you’re OK with its limitations.
