ARIA
In plain terms
Attributes that make web content accessible to assistive technologies.
Going deeper
ARIA (Accessible Rich Internet Applications) adds roles and properties so screen readers understand dynamic and custom UI. It bridges gaps native HTML can't cover.
Under the hood
Use native semantic HTML first; ARIA supplements for custom widgets, and misused ARIA can harm accessibility.
Examples
Screen-reader support, custom dropdowns, role/aria-label attributes, WCAG compliance.
Think of it like...
Like adding braille labels so everyone can navigate the interface.
