ARIA Landmark roles provide a powerful way to identify the layout and structure of portal and application pages. By classifying and labeling sections of a page, they make it possible to programmatically represent structural information that is conveyed visually through the layout. Screen readers use landmark roles to enable keyboard navigation to important sections of a page. Landmark regions can also be used as targets for "skip links" and by browser extensions to improve keyboard navigation.
The following image illustrates a possible landmark structure for a portal or application page.
