The WAI-ARIA (Active Rich Internet Applications) is a W3C recommendation that defines a way to make Web content and Web applications more accessible to people with disabilities. It is especially useful with dynamic content and advanced user interface controls (such as toolbars, treeviews, menubars, etc) used by the so-called “desktop-like” web applications and implemented with HTML, JavaScript, and related technologies.

WAI-ARIA provides a framework for adding attributes to identify features for user interaction, how they relate to each other, and their current state. In addition to this, WAI-ARIA describes navigation techniques to mark regions and common Web structures as “landmarks”, or enrich their semantics.

This goal is achieved by providing web developers with a set of attributes (roles, states and properties), and documenting “expected behaviors” to provide keyboard navigation.
