ARIA
Definition
Accessible Rich Internet Applications (ARIA) is a set of attributes that define ways to make web content and web applications more accessible. ARIA is strictly meant to bridge gaps where native semantic HTML falls short.
Explain Like I'm New
A set of special tags you add to complex custom UI components (like a custom dropdown) to explicitly tell screen readers exactly what the component is and what state it is in.
Terminal Output

First Rule of ARIA:
No ARIA is better than bad ARIA.
Always prefer native semantic HTML elements over ARIA attributes whenever possible.
