What are the main principles of WCAG?

The main principles of the Web Content Accessibility Guidelines (WCAG) are centered around creating web content that is inclusive and usable for individuals with disabilities. The correct choice highlights four fundamental principles: perceivable, operable, understandable, and robust.

• Perceivable means that information and user interface components must be presented to users in ways they can perceive. This includes providing text alternatives for non-text content, ensuring that content can be presented in different ways without losing meaning.

• Operable entails that users must be able to interact with the user interface. This means all functionalities must be accessible via a keyboard, and users must have enough time to read and use content, among other considerations.

• Understandable speaks to the clarity of information and interface operations. Content should be clear and consistent, making it easier for users to navigate and understand the interactions.

• Robust means that content must be robust enough to be interpreted reliably by a variety of user agents, including assistive technologies. This ensures that as technologies evolve, the content remains accessible and usable.

These principles are essential for ensuring that web development meets the standards of inclusivity and helps to break down barriers for users with diverse abilities.
