Include required ARIA attributes for roles

Certain ARIA roles are incomplete without their required attributes, preventing assistive technologies from correctly communicating the element's state or value.

Quick Reference

• Ensure attributes like aria-valuenow for sliders are present

Check

Verify that all ARIA roles have their mandatory attributes as defined by the WAI-ARIA specification.

Fix

Add the missing required ARIA attributes to elements with specific roles (e.g., aria-valuenow for role="slider").

Explain

Explain how required ARIA attributes provide critical state information that screen readers need to function correctly.

Code Review

Review the rendered markup and interactive states that affect Include required ARIA attributes for roles. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
