XHTML (Extensible Hypertext Markup Language)

XHTML (Extensible Hypertext Markup Language) is a format used to create web pages, combining the structure of HTML with the strict rules of XML. It ensures that webpage code is well-formed, consistent, and easier for web browsers and other tools to interpret. XHTML enforces proper syntax, like closing all tags and using lowercase letters, which improves compatibility and accessibility. It is more rigorous than HTML, making web development more reliable and maintainable while still delivering the same visual content and functionality on websites.
