What are the four principles of WCAG known as?

The four principles of WCAG, known as POUR, stand for Perceivable, Operable, Understandable, and Robust. Each principle serves as a fundamental guideline to assist in creating accessible web content.

Perceivable means that information and user interface components must be presented to users in ways that they can perceive. This includes providing text alternatives for non-text content and ensuring that content is adaptable for different presentations.

Operable emphasizes that interface components and navigation must be operable by users. This principle focuses on making sure that users can interact with all elements of the website, regardless of the input method they may use, such as keyboard, mouse, or touch.

Understandable refers to ensuring that information is clear and easy to understand. This means both the text content and the user interface should be understandable to all users. Instructions should be clear, and jargon should be minimized to ensure clarity.

Robust emphasizes the importance of content being robust enough to work across a wide variety of user agents, including assistive technologies. This means content should be developed with future technologies in mind to remain accessible.

The other options do not represent the core principles of WCAG, making them less relevant in this context. Understanding the POUR principles is essential for anyone involved in web accessibility
