accessibility

Audit web accessibility by evaluating your page against WCAG 2.1 guidelines, focusing on Perceivable, Operable, Understandable, and Robust principles. This includes detailed checks for text alternatives, color contrast, keyboard navigation, focus visibility, form labeling, error handling, and ARIA usage.

The best way to test keyboard navigation and focus visibility is using the provided manual testing checklists. These checklists evaluate operability by verifying that users can navigate interactive elements using only a keyboard and that focus indicators are clearly visible.

ARIA usage affects web accessibility by providing semantic information to screen readers when native HTML is insufficient. Proper ARIA implementation ensures that dynamic content and complex UI components are understandable and operable for users relying on assistive technologies.

You cannot rely on automated testing alone to verify WCAG AA standards. While automated tools catch many technical errors, manual testing and screen reader command references are required to ensure broad usability for users with visual, auditory, motor, or cognitive impairments.

You need to check color contrast and text alternatives during web development whenever adding visual content. These checks ensure that information is perceivable by users with visual impairments, meeting WCAG 2.1 requirements for text alternatives and sufficient color contrast ratios.
