Writing valid HTML adheres to which WCAG principle?
- Perceivability
- Operability
- Understandability
- Robustness
Explanation: Writing valid HTML adheres to the Robustness principle of the Web Content Accessibility Guidelines (WCAG). The Robustness principle emphasizes the importance of creating web content that can be reliably interpreted by a wide range of user agents, including assistive technologies like screen readers, browsers, and other devices. Valid HTML ensures that web pages are structured correctly according to the HTML specifications, which promotes consistency and predictability in how user agents interpret and present the content. By adhering to HTML standards, developers can minimize compatibility issues and ensure that their content is accessible to users regardless of the technology or device they use to access the web. Valid HTML also contributes to the overall reliability and interoperability of web content, supporting the accessibility goals outlined in the WCAG. Therefore, writing valid HTML is essential for meeting the Robustness criterion of WCAG and promoting a more inclusive and accessible web environment for all users.
