Introduction to XHTML
In this section you will learn the brief introduction of XHTML, what is the difference between HTML and XHTML, the reason why XHTML become an important web development standard, and the basic syntax of XHTML.
What is XHTML
XHTML, stands for Extensible HyperText Markup Language, is used to describe the XML version of HTML. The first release of, XHTML1.0, is published by W3C on January 26th, 2000. XHTML has a high degree of relationship with both HTML and XML which are in SGML family, and is expected to be the description language of Web contents that can be processed by XML-compliant tools. In the near future, all web pages using HTML will have to migrate to XHTML, which is stricter, cleaner, and consider as a standard.
XHTML 1.1
The most updated version of XHTML is 1.1, which is designed to accommodate extensions through existing XHTML modules and techniques for developing new modules. To be easier to describe, as the XHTML contains many functions to support web development, W3C tried to make it more convenient to use by separating the XHTML into small portions (called module.) Each module can combine with other XML-compliant or can support other devices. Also, the latest version, which means to serve the future extension of XHTML family, tries to minimize the deprecated element from the previous version. The W3C recommendation for version 1.1, a module-based concept for XHTML, has already been published on 31 May 2001.
