👉 XHTML (Extensible HyperText Markup Language) is a web markup language that extends HTML by adding stricter rules and features to ensure better structure, validation, and compatibility across different browsers. Unlike HTML, which allows for more permissive and sometimes inconsistent markup, XHTML enforces a strict set of rules based on XML standards, requiring all tags to be properly closed and nested. This leads to more predictable and maintainable web pages, as the structure is more rigid and easier to parse by browsers and servers. XHTML also supports attributes, namespaces, and more complex data types, making it suitable for creating robust and scalable web applications. However, the strictness of XHTML can sometimes make it more challenging to implement, especially for developers accustomed to HTML's more flexible nature.
