Extensible Hypertext Markup Language (XHTML) is part of the family of XML markup languages. It mirrors or extends versions of the widely used Hypertext Markup Language (HTML), the language in which Web pages are formulated.
While HTML, prior to HTML5, was defined as an application of Standard Generalized Markup Language (SGML), a flexible markup language framework, XHTML is an application of XML, a more restrictive subset of SGML. XHTML documents are well-formed and may therefore be parsed using standard XML parsers, unlike HTML, which requires a lenient HTML-specific parser.
XHTML 1.0 became a World Wide Web Consortium (W3C) Recommendation on January 26, 2000. XHTML 1.1 became a W3C Recommendation on May 31, 2001. The standard known as XHTML5 is being developed as an XML adaptation of the HTML5 specification.
XHTML 1.0 is "a reformulation of the three HTML 4 document types as applications of XML 1.0". The World Wide Web Consortium (W3C) also continues to maintain the HTML 4.01 Recommendation, and the specifications for HTML5 and XHTML5 are being actively developed. In the current XHTML 1.0 Recommendation document, as published and revised to August 2002, the W3C commented that, "The XHTML family is the next step in the evolution of the Internet. By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward and future compatibility."
HyperText Markup Language, commonly referred to as HTML, is the standard markup language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone technology, used by most websites to create visually engaging web pages, user interfaces for web applications, and user interfaces for many mobile applications.Web browsers can read HTML files and render them into visible or audible web pages. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language.
HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items.
The language is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>
). Browsers do not display the HTML tags and scripts, but use them to interpret the content of the page.

Should I learn XHTML or HTML5? HTML was the first programming language for creating webpages. I know, and HTML 5 is the latest and greatest version of that. But I've heard I should learn XHTML instead. XHTML is a more precise version of HTML 4. However, it was never as popular as HTML 4. I thought programmers loved precise programming languages. Not if it is a pain in the butt to code and debug. It's a rather unforgiving software language, such as the convoluted implementation of the doctype definition. I guess that's why HTML5 is the world wide web consortium standard. The two aren't complete opposites. For example, HTML5 picked up the validation support XHTML had. I heard HTML5 has stricter coding standards than HTML 4. In that regard, it copied from XHTML. The Wild West nature ...

Things do go wrong, it's not long since I've been blue,
But I know the remedy, I can see just what to do...
Don't be a coward, don't be yellow,
It always pays to be mellow,
Stay cool, stay free and then you will see,
It's best to stay mellow...
I was upset and in debt with no money,
But I did not stay sad, it's not that bad, so remember...
Oh if you are down in the town with no bus fare,
