Web development has evolved significantly over the years, and developers have constantly strived to create websites that are not only visually appealing but also easy to use and navigate. XHTML is one of the most popular web development languages used today, and it is crucial for developers to ensure that their websites are compliant with the XHTML standard. This is where the XHTML validator comes into play.

XHTML stands for eXtensible HyperText Markup Language, and it is a markup language used to create web pages. EXtensible HyperText Markup Language is a combination of HTML and XML, and it is designed to be more modular, extensible, and well-formed than HTML. XHTML is stricter than HTML and has a set of rules that developers must follow to ensure that their web pages are valid.
