XHTML (Extensible Hypertext Markup Language) was developed to enhance HTML. HTML is a good markup language that has served the web well but at a certain stage, innovations planned for the web required more of HTML. Thus, in 2000, XML rules were added to HTML to beef it up. The result, XHTML 1.0, retains almost all of HTML 4.01. From a markup perspective, all the elements and attributes remain the same. This continuity from HTML into XHTML is key because it means that XHTML is backward-compatible when written correctly.
