What Is ARIA?
ARIA stands for Accessible Rich Internet Applications. It's a set of attributes you can add to HTML elements to provide extra information to assistive technology. ARIA is useful for complex interactive components like tabs, modals, and dropdown menus that don't have native HTML equivalents. But ARIA is not a substitute for semantic HTML. The first rule of ARIA is literally: don't use ARIA if you can use a native HTML element instead. Misused ARIA is worse than no ARIA at all.
