XHTML

XHTML (Extensible HyperText Markup Language) is a markup language maintained by the World Wide Web Consortium (W3C) as a strict form of HTML used to create websites. It is an XML-based language that is designed to replace HTML in order to enable the web to scale to larger projects.

It is used for describing the structure of web documents through the use of tags that define the meaning and presentation of text. XHTML 1.0 was released in 2000 as an attempt to create an XML version of HTML 4.01 and has since been followed by other versions. XHTML acts as a bridge between HTML and XML and is designed to be compatible between various XML languages.

XHTML allows developers to create simple and effective web pages. Documents written in this language are easier to read and maintain as compared to HTML, as XHTML requires the use of proper structure. This makes sure that documents written in XHTML are valid and are more easily parsed by various web browsers.

XHTML is an important part of the modern web architecture and is widely used in web content development. It is an essential building block for web application development and is supported by most web browsers.
