Understanding XHTML: The Full Form

The question asks for the full form of the acronym XHTML. Understanding common acronyms in web development is important.

What is XHTML?

XHTML stands for Extensible HyperText Markup Language. It is a family of XML markup languages that mirror or extend versions of the widely used HyperText Markup Language (HTML).

While HTML is primarily used for structuring content on the web, XHTML brings stricter syntax rules derived from XML, aiming for cleaner and more structured web documents.
