Aria Roles

Definition

Aria roles are a set of attributes used in web development that define the accessibility properties of elements in web applications, especially for users with disabilities. These roles help screen readers and other assistive technologies understand the purpose of specific parts of a webpage, making it more navigable and usable. By effectively utilizing aria roles, developers can create more responsive and inclusive web designs that cater to a broader audience.
