This is a classic page structure with a header, a navigation, main content, maybe some complementary content on the margin and a footer. We do have correct markup for these parts.

When creating layouts, designers and technologists must be aware of ARIA landmarks - HTML elements that define regions of a page which help a machine to better interpret the content.

"Landmarks provide a powerful way to identify the organization and structure of a web page. The structural information conveyed visually to users should be represented programmatically in the markup using landmark roles."

<p>Examples of ARIA Landmarks as can be seen on the WCAG webpage linked below.</p>

Landmarks that are available for designers and developers include navigation, footer, banner, main, article, section, header, complimentary, aside, form and region.

Finally, unless the landmark begins with a header tag, each landmark must be labelled using an aria-label.
