In ARIA, what is the role of landmarks?

The role of landmarks in the Accessible Rich Internet Applications (ARIA) specification is to identify significant sections of a webpage. This allows assistive technologies, such as screen readers, to help users navigate through a web page more easily. By marking specific regions of the page, such as navigation, main content, and complementary information, landmarks provide a way for users to jump directly to these areas without having to traverse the entire document linearly.

This is particularly beneficial for individuals with motor impairments or cognitive disabilities, as it gives them greater control over their navigation experience. The use of landmarks empowers these users, enhancing their ability to consume content effectively and efficiently. Consequently, identifying significant webpage sections is essential for creating a user-friendly and accessible web experience, which fully aligns with the principles of web accessibility.
