Accessible Rich Internet Applications (ARIA)
The ARIA standard, or Accessible Rich Internet Applications, is a technology that improves the accessibility of web applications, including those built with Drupal. It provides special attributes to use in HTML code to indicate to screen readers and other assistive technologies how to interact with interactive elements, such as dropdown menus or modals, in a way that is more understandable for users with disabilities.
ARIA plays a vital role in enhancing the user experience for people with disabilities by making websites more accessible and interactive.
It is also a standard maintained by the W3C.
