aria | Accessibility Support

ARIA stands for Accessible Rich Internet Applications. This standard is used to augment other technologies such as HTML and improve accessibility.

Features and Tests

Features represent the various aspects of a technology. In HTML a feature might be an element or attribute. In CSS a feature might be a property. In ARIA a feature might be an attribute.

A test is a manual verification that a feature works like it is supposed to. The expectations of a feature might change in different contexts or when combined with different features and technologies. Therefore each feature can have many tests, and a test can be shared between many features and technologies. In general, a test should be specifically tailored to measure a single outcome.
