Multiple Choice Questions on WAVE and Lighthouse Accessibility Tools

📚 Quick Study Guide

• 🌐 WAVE (Web Accessibility Evaluation Tool): A web accessibility evaluation tool developed by WebAIM. It's a visual tool that injects accessibility icons directly into your webpage.
• 🔍 WAVE Features: Identifies accessibility errors and alerts, structural elements, and ARIA features. It does NOT require you to submit your page to a remote server.
• 🛠️ Lighthouse (Google): An open-source, automated tool for improving the quality of web pages. It has audits for performance, accessibility, progressive web apps, SEO and more.
• 🚦 Lighthouse Accessibility Score: A weighted average of all accessibility audits. Aim for a score of 100, but remember that automated testing can only catch approximately 20-40% of accessibility issues.
• 💡 Common Accessibility Issues Detected: Low contrast text, missing alt text for images, improper use of ARIA attributes, and form elements without labels.
• 📝 Benefits of Using Both: WAVE provides immediate, visual feedback on your page. Lighthouse offers a broader range of audits and integrates directly into Chrome DevTools. Using both tools provides a more comprehensive accessibility review.
• ✅ Important Note: Automated testing should be complemented with manual testing, including keyboard navigation and screen reader testing.
