Web Accessibility Quiz: Test Your Knowledge

📚 Quick Study Guide

• 🔍 WCAG (Web Content Accessibility Guidelines): These are the internationally recognized standards for web accessibility. They are organized into four principles: Perceivable, Operable, Understandable, and Robust (POUR).
• ⌨️ Keyboard Navigation: Ensure all interactive elements are navigable using a keyboard alone. This is crucial for users who cannot use a mouse.
• 🖼️ Alternative Text (Alt Text): Provide descriptive alt text for images so screen readers can convey the image's content to users with visual impairments.
• ♿ ARIA (Accessible Rich Internet Applications): ARIA attributes enhance the accessibility of dynamic web content and advanced UI controls developed with HTML, CSS, and JavaScript.
• 🌐 Semantic HTML: Use semantic HTML elements (e.g., `
  `, `
• 🎨 Color Contrast: Ensure sufficient color contrast between text and background colors to meet WCAG guidelines and improve readability for users with low vision. The contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text.
• ✍️ Clear and Simple Language: Use clear, concise language that is easy to understand, avoiding jargon and complex sentence structures.
