Providing text alternatives for non-text content adheres to which WCAG principle?
- Perceivability
- Operability
- Understandability
- Robustness
Explanation: Providing text alternatives for non-text content adheres to the Perceivability principle of the Web Content Accessibility Guidelines (WCAG). Perceivability emphasizes ensuring that information and user interface components are presented in ways that can be perceived by all users, including those with disabilities. Non-text content such as images, videos, graphs, and charts may not be accessible to users who are blind or have low vision, or those who have difficulty processing visual information. Text alternatives, such as alt text for images or captions for videos, provide a means for conveying the content and function of non-text elements to users who cannot perceive them visually. This allows assistive technologies, such as screen readers, to interpret and present the content to users with disabilities, ensuring equal access to information. By providing text alternatives, web content becomes perceivable by a broader range of users, regardless of their abilities or the technologies they use to access the web. Therefore, incorporating text alternatives for non-text content is essential for meeting the Perceivability criterion of WCAG and improving the accessibility of web content for all users.
