HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as heading.
The <h1> through <h6> elements are headings for the sections with which they are associated. They should not be empty, for example <h1></h1> is invalid.
The heading role defines this element as a heading to a page or section, and is implicit in tags <h1> to <h6>.
The heading role indicates to assistive technologies that this element should be treated like a heading. Screen readers would read the text and indicate that it is formatted like a heading.
This ARIA role is only needed to add that role to a generic element like <div>, for example:
<div role="heading" aria-level="1">This is a main page heading</div>
This defines the text in the <div> to be the main heading of the page, indicated by being level 1 via the aria-level attribute. Opt for using the <h1> (thru <h6>) element instead:
<h1>This is a main page heading</h1>
