How do you audit and remediate WCAG 2.2 AA accessibility failures in complex web apps?
❓ Interview Prompt: Explain WCAG 2.2 AA guidelines, automated testing (axe-core, Lighthouse), color contrast minimums (4.5:1), and focus appearance rules.
Ensuring WCAG 2.2 Level AA compliance requires systematically auditing and fixing accessibility barriers:
Core Criteria to Remediate:
1
Color Contrast (1.4.3): Text must maintain minimum 4.5:1 contrast ratio against background.
2
Focus Appearance (2.4.13): Interactive elements must display a high-contrast focus indicator ring.
3
Target Size (2.5.8): Interactive touch targets must be at least 24x24 CSS pixels.
Code Implementation Example
css
/* High-contrast focus indicator ring enforcing WCAG 2.2 compliance */
:focus-visible {
outline: 3px solid #005fcc;
outline-offset: 2px;
}💡WCAG 2.2 compliant focus indicator styling.
🎯 Interview Key Takeaway
Audit applications against WCAG 2.2 AA guidelines, enforcing 4.5:1 color contrast and visible focus indicators.
