ARIA Landmarks

Using appropriate headings to identify the structure of a web page is essential for people who use assistive technologies, like screen readers; however, heading structure can become cumbersome when applied to complex pages with multiple regions, each with their own nested headings. ARIA landmarks help by adding additional markup to identify region level-structure, which allows headings to be reserved for providing structure within a region. Screen reader users can navigate by landmark, providing a way to jump from region to region.
