What does html refer to?
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.
Hypertext is a way of organizing information that associates text and graphics in the text with other information media through hyperlinks. These interrelated information media may be in the same text, may be other files, or may be files on a computer that are geographically distant. This way of organizing information connects information resources distributed in different locations in a random manner, making it easier for people to find and retrieve information.
HTML version
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 has the following versions in history:
①HTML 1.0: Released as an Internet Engineering Task Force (IETF) working draft in June 1993.
②HTML 2.0: Released as RFC 1866 in January 1995, it was declared obsolete after its release in June 2000.
③HTML 3.2: January 14, 1997, W3C recommended standard.
④HTML 4.0: December 18, 1997, W3C recommended standard.
⑤HTML 4.01 (minor improvement): December 24, 1999, W3C recommended standard.
⑥HTML 5: HTML5 is recognized as the next generation Web language. It has greatly improved the capabilities of the Web in terms of rich media, rich content and rich applications. It is hailed as an important driving force that will eventually change the mobile Internet. Internet Explorer 8 and earlier versions are not supported.
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.
Features
Hypertext markup language document production is not very complicated, but it is powerful. Supports the embedding of files in different data formats, which is one of the reasons for the popularity of the World Wide Web (WWW). Its main features are as follows:
Simplicity: Hypertext Markup Language version upgrade adopts superset method, making it more flexible and convenient .
Extensibility: The wide application of hypertext markup language has brought about requirements for strengthening functions and adding identifiers. Hypertext markup language adopts the method of subclass elements to ensure system expansion.
Platform independence: Although personal computers are popular, there are many people using other machines such as MAC. Hypertext Markup Language can be used on a wide range of platforms, which is another reason for the popularity of the World Wide Web (WWW).
Versatility: In addition, HTML is the universal language of the Internet, a simple and universal all-purpose markup language. It allows web page producers to create complex pages that combine text and images, and these pages can be viewed by anyone else on the Internet, regardless of the type of computer or browser used.
