Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as submit.
The button role is used to make an element appear as a button control to a screen reader and can be applied to otherwise non-interactive elements like <div>. If you’re already using an <input> element whose type is submit, then it’s redundant to apply it the role button, as that’s implicit.
<!-- Instead of this --> <input type="submit" role="button">Buy</button> <!-- Do this --> <input type="submit">Buy</button>
25,000 HTML checks per month. Fully automated.
Save time using our automated web checker. Let our crawler check your web pages on the W3C Validator.
