HTML Checking for Large Sites

Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.

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>
