ARIA

does without ARIA telling it. ARIA 1.2 is the current published standard (June 2023); ARIA 1.3 is in editor's draft. The core concepts: roles (role="button", role="dialog", role="navigation", role="tablist", role="combobox" — declare what kind of widget an element is), states (aria-expanded, aria-checked, aria-selected, aria-pressed — declare the widget's current state), properties (aria-label, aria-labelledby, aria-describedby, aria-required, aria-invalid — declare unchanging characteristics), and live regions (aria-live="polite" or "assertive" — announce dynamic content changes). The cardinal rule, articulated in ARIA's official authoring practices, is "no ARIA is better than bad ARIA" — incorrect ARIA actively misleads users worse than no ARIA at all. The corollary: use native HTML elements wherever possible (a real

), reach for ARIA only when no native element fits the design. Practical examples: a custom tab interface needs role="tablist" on the container, role="tab" on each tab with aria-selected indicating the current tab, aria-controls pointing to the corresponding tab panel, and role="tabpanel" on the panels; a modal dialog needs role="dialog", aria-modal="true", aria-labelledby pointing to the dialog title, and focus management on open and close. The W3C ARIA Authoring Practices Guide (apg-aria.com or w3.org/WAI/ARIA/apg) is the canonical reference with implementation patterns for every common widget. Testing requires both axe-core/Lighthouse for automated checks and manual screen-reader testing — NVDA on Windows, VoiceOver on macOS and iOS, TalkBack on Android. For Digital Experience Platforms, ARIA is what makes custom-designed interactive experiences accessible to assistive-technology users.

ARIA discipline under a Magic Quadrant DXP: Centralpoint authors ARIA-compliant interactive components — the discipline that makes custom-designed experiences accessible to screen-reader users without exception. Twenty-five years of accessibility maturity underpins the Gartner Magic Quadrant DXP positioning. ARIA-enriched components run on-premise, lineage is audit-graded, and accessible experiences deploy through one line of JavaScript.
