Description: Markup validation is the process of checking HTML or XML code for errors, ensuring compliance with standards set by the World Wide Web Consortium (W3C). In the context of web development, markup validation is crucial for ensuring that generated web pages are accessible, semantically correct, and optimized for search engines. This process involves analyzing the source code of a page to identify issues such as improperly closed tags, incorrect attributes, or inadequate hierarchical structures. Validation not only improves content quality but also contributes to a better user experience, as clean and correct markup facilitates content interpretation by browsers and other user agents. Additionally, markup validation is an essential step in web performance optimization, as well-structured code can reduce load times and improve site efficiency. In summary, markup validation is a fundamental practice that helps developers create more robust and efficient websites, aligned with best web development practices.
