Accessibility Checking for Large Sites

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

A best practice is to guarantee that there is only one primary landmark for navigating to the page’s principal content, and if the page has iframe components, each should contain either no landmarks or a single landmark.

If a website’s material is divided into one or more high-level parts, screen reader users will find it much easier to navigate. It is difficult to locate content outside of these categories, and its purpose may be obscure.

Historically, HTML lacked essential semantic markers, such as the ability to define page sections as the header, navigation, primary content, and footer. Using both HTML5 elements and ARIA landmarks in the same element is a best practice, but as browser support grows, the future will favor HTML areas.

What this Accessibility Rule Checks
