A.5 WCAG 2.1 Success Criterion 1.3.6 – Identify Purpose

The purpose of user interface components, icons and certain sections can be identified by user agents. For example, Accessible Rich Internet Application (ARIA) landmarks should be used to identify regions of a page, so that assistive technologies can be used to make the content more understandable.

Before Rectification

Without setting the ARIA landmark roles, assistive technologies cannot easily recognise different regions of the webpage to provide customisation for the user.

After Rectification

The ARIA landmark roles are assigned to identify different regions of the page. Assistive technologies can help the user by adding icons or changing the styles of individual webpage components.
