Accessibility Checking for Large Sites

Rocket Validator integrates axe-core version 4.6, into an automated web site scanner.

Document should not have more than one main landmark

The core content of the page should only have one main landmark, and if the page contains iframe components, each one should either have no landmarks or just one. This is considered best practice.

If all of the content is divided up into one or more high-level divisions, screen reader users will have much easier time navigating a website. Outside of these categories, information can be hard to access and has an uncertain purpose.

Some essential semantic markers, such the ability to designate portions of the page as the header, navigation, primary content, and footer, have historically been absent from HTML. Although it’s recommended to combine HTML5 elements with ARIA markers in a single element, HTML regions will eventually prevail as browser support grows.

What this Accessibility Rule Checks

Makes sure there is just one primary landmark in the document.
