HTML stands for Hypertext Markup Language and is a markup language. It includes a series of tags. These tags can unify the document format on the network and connect scattered Internet resources into a logical whole. HTML text is descriptive text composed of HTML commands. HTML commands can describe text, graphics, animations, sounds, tables, links, etc.

HTML Version

Since the early days of the Web, multiple HTML versions have been developed:

##HTML52012 HTML5 is recognized as the next generation Web language, which has greatly improved the Web's capabilities in rich media, rich content and rich applications, and is hailed as an important driving force that will eventually change the mobile Internet. Internet Explorer 8 and earlier versions are not supported. XHTML52013##

HTML is a syntax rule used to mark how Web information is displayed and other characteristics. It was originally invented in 1989 by Tim Berners-Lee of CERN. HTML is based on the older language SGML definition and simplifies the language elements. These elements are used to tell the browser how to display data on the user's screen, so they have been supported by various web browser manufacturers for a long time.

HTML plays an important role and has an important position in the rapid development of the Web. However, with the deepening of network applications, especially e-commerce applications, the shortcomings of HTML's oversimplification quickly became apparent: HTML is not extensible. HTML does not allow application developers to define custom markup for specific application environments. HTML can only be used for information display. HTML can set the display mode of text and pictures, but it has no semantic structure, that is, HTML displays data according to layout rather than semantics. With the development of network applications, various industries have different needs for information, and these different types of information may not always be displayed in the form of web pages. For example. When searching for data via a search engine, there are advantages to displaying data semantically rather than layout-wise.

In short, the shortcomings of HTML make it poor interactivity and ambiguous semantics. These shortcomings are difficult to adapt to the requirements of the rapid development of the Internet. Therefore, a standard, concise, rigorously structured and highly extensible XML was created.
