Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as empty.
The id attribute is used to identify a single element within a document, it’s not required, but if used it must be unique, and must not be an empty string.
50,000 Accessibility and HTML checks per month. Fully automated.
Let our automated scanner check your large sites using Axe Core and W3C Validator.
