What is a .xhtml file?

XHTML (Extensible Hypertext Markup Language) is a markup language that is a stricter and cleaner version of HTML. It is designed to be a more robust and well-formed language, adhering to XML (Extensible Markup Language) standards. This means that XHTML documents must follow specific rules regarding syntax, such as proper nesting of elements, mandatory closing tags, and proper attribute quoting. The goal of XHTML is to create web pages that are more consistent and easier to parse by machines, leading to improved interoperability and accessibility. XHTML documents are typically used for creating web pages, but they can also be used for other purposes, such as creating documents for mobile devices or for use in other applications that require structured data. Because of its strict syntax, XHTML can be validated to ensure that it is well-formed, which can help to prevent errors and improve the overall quality of the document. While HTML5 has become the dominant standard for web development, understanding XHTML can still be valuable, especially when working with older systems or when a stricter markup language is required.
