Q1: What are the main principles of WCAG?

  • A1: WCAG is based on four main principles known as POUR:
  1. Perceivable (P): Information must be presented in a way users can perceive.
  2. Operable (O): User interface components and navigation must be operable.
  3. Understandable (U): Information and operation of the user interface must be understandable.
  4. Robust (R): Content must be robust and reliably interpreted by various user agents.

Q2: What does “Perceivable” include?

  • A2: Perceivable involves providing text alternatives for non-text content, captions for multimedia, adaptable content, and distinguishable information.

Q3: What does “Operable” mean in WCAG?

  • A3: Operable focuses on keyboard accessibility, providing sufficient time for users, avoiding content causing discomfort, and designing consistent and predictable interfaces.

Q4: What falls under the “Understandable” principle?

  • A4: Understandable includes readable and predictable text, input assistance for error prevention and correction, and maintaining consistent navigation and functionality.

Q5: What is the significance of the “Robust” principle?

  • A5: The “Robust” principle ensures content is reliably interpreted by user agents, involving the use of valid code, compatibility with current/future technologies, and providing fallbacks for unsupported content.

Q6: How is WCAG conformance measured?

  • A6: WCAG success criteria are categorized into three levels: A (lowest), AA, and AAA. Conformance is determined by meeting the specified success criteria.

Q7: How can websites benefit from WCAG compliance?

  • A7: WCAG compliance enhances website accessibility, making content and functionality available to a broader audience, including users with disabilities.
