HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as aside.
Using the <aside> element will automatically communicate a section has a role of complementary, so specifying the role="complementary" is redundant.
6,250 HTML checks per week. Fully automated.
Save time using our automated web checker. Let our crawler check your web pages on the W3C Validator.
