The Key to a successful Web Standard is four different but well known standards.
Definition of HTML: The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages.
Purpose of HTML: 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 quotes and other items. HTML is written in form of elements which read HTML consisting of tags enclosed in angle brackets like <html>. HTML is the main markup language for creating web pages and other information that can be displayed in a web browser. Web browsers can also refer to cascading style sheets to define the appearance and layout of text and other material. The W3C, maintainer of both the HTML and CSS standards, encourages the use of CSS over explicit presentational HTML markup. HTML is the most common used web standard which is read by JavaScript.
HTML has been developing since 1955.
Definition of CSS: CSS is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML.
Purpose of CSS: Web browsers can also refer to Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicit presentational HTML markup.
These Styled Sheets were developed in the 1980's.
Definition of XML: An XML document is a string of characters. Almost every legal Unicode character may appear in an XML document. Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
Purpose of XML: As of 2009, hundreds of XML-based languages have been developed.L. XML-based formats have become the default for many office-productivity tools, including Microsoft Office (Office Open XML), OpenOffice.org and LibreOffice (OpenDocument), and Apple's iWork.
Definition of XHTML: is a family of XML markup languages that mirror or extend versions of the widely used as Hypertext Markup Language (HTML), the language in which web pages are written.
Purpose of XHTML: There are various differences between XHTML and HTML. The Document Object Model is a tree structure that represents the page internally in applications, and XHTML and HTML are two different ways of representing that in markup. It was adopted to achieve maximum results and develop HTML as a web standard. It was developed in the Year 2000.
