What are the main principles of the Web Content Accessibility Guidelines (WCAG)?

The main principles of the Web Content Accessibility Guidelines (WCAG) are Perceivable, Operable, Understandable, and Robust. These principles serve as a foundation for making web content accessible to individuals with various disabilities.

Perceivable means that information and user interface components must be presented in ways that users can perceive. This includes providing text alternatives for non-text content, ensuring that content can be resized, and using sufficient contrast to improve visibility.

Operable emphasizes that users must be able to navigate and interact with the content. It requires that all functionality be accessible via a keyboard and that users have enough time to read and use the content.

Understandable ensures that both the content and the operation of the user interface should be clear and easy to understand. This includes using clear language and providing help when needed.

Robust relates to the compatibility of the content with current and future user agents, including assistive technologies. Content should be built in a way that it can be reliably interpreted by different devices and tools, ensuring ongoing accessibility over time.

These principles create a comprehensive framework aimed at accommodating a wide range of users, including people with disabilities, thereby fostering an equitable digital environment. Other options do not reflect the established principles as outlined by WCAG.
