FAQPage Schema
How do I audit web accessibility for WCAG and ARIA compliance?▼

To audit web accessibility for WCAG and ARIA compliance, capture ARIA snapshots, inspect the AX tree for structural issues, and validate keyboard navigation. This generates actionable findings aligned with WCAG checklist items for remediation.

What is an AX tree analysis for screen reader compatibility?▼

AX tree analysis inspects the accessibility tree to evaluate structure, relationships, and visibility issues. It reveals how screen readers interpret page elements, exposing gaps in roles and attributes that hinder screen reader compatibility.

Can I test keyboard navigation and focus order across UI patterns?▼

Yes, you can test keyboard navigation and focus order by validating keyboard operability across UI patterns. This checks whether users can navigate and interact with elements using only keys, ensuring proper focus management.

Does browser-devtools-cli support generating ARIA snapshots?▼

Yes, browser-devtools-cli supports generating ARIA snapshots to capture ARIA attributes and roles. This process flags accessibility gaps directly from the browser environment for further WCAG validation.

What is the best way to align accessibility findings with a WCAG checklist?▼

The best way to align accessibility findings with a WCAG checklist is to map captured ARIA snapshots and AX tree issues directly to WCAG checklist items. This provides specific remediation steps for each compliance failure.
