WCAG Quiz: Testing Your Knowledge of Web Accessibility Standards

📚 Quick Study Guide

• 🌐 WCAG Principles (POUR):
  • perceivable: Information and UI components must be presentable to users in ways they can perceive.
  • operable: UI components and navigation must be operable.
  • understandable: Information and the operation of the UI must be understandable.
  • robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
• 📏 Levels of Conformance: WCAG defines three levels of conformance: A, AA, and AAA. Each level builds upon the previous one.
• 🖼️ Alternative Text (Alt Text): Provide descriptive alt text for images so screen readers can convey the image's content to users.
• ⌨️ Keyboard Accessibility: Ensure all functionality is available via a keyboard.
• 🎨 Color Contrast: Maintain sufficient color contrast between text and background for readability. The contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text.
• 📝 Forms: Label form elements clearly and provide instructions for completing forms.
• 🧭 Navigation: Provide clear and consistent navigation mechanisms.
