The file extension XHTML is associated with developer files which are created using Hypertext Markup Language or HTML. HTML is used to create web pages and other components which can be viewed in the online environment and is written in a markup language which conforms to ISO (International Standards Organization) standard publishing language for the World Wide Web.
XHTML stands for Extensible Hypertext Markup Language and is a document type which is XML based and is used as a language for content which must conform to XML (Extensible Markup Language) with integrated HTML 4 user agents. Extensible Markup Language uses HTML tags and maintains the quality of HTML while retaining commonly used features. The commonly used features are kept while complex features of HTML are removed to make the design of various software applications more cost effective. XML also allows for the easy introduction of new element attributes while XHTML modules accommodate the new attributes.
XHTML files are a web file type which stores XHTML documents that have been written to perform more efficiently than the conventional HTML document model. The XML based documents can be immediately accessed and viewed using Extensible Markup Language tools. The documents can also be integrated with a variety of XHTML environments.
