What does an HTML document mean?
Hypertext markup language

Hypertext Markup Language, Chinese is also Hypertext Markup Language. HTML(HyperTextMark-upLanguage), namely hypertext markup language, is the description language of WWW. The purpose of designing HTML language is to connect the text or graphics stored in one computer with the text or graphics stored in another computer to form an organic whole. People don't have to consider whether the specific information is on the current computer or on other computers on the network. We just need to click an icon in the document with the mouse, and the Internet will immediately go to the content related to this icon, which may be stored in another computer on the network. HTML text is descriptive text composed of HTML commands, which can explain words, graphics, animations, sounds, tables, links and so on. The structure of HTML includes a header and a body, in which the header describes the information needed by the browser and the body contains the specific content to be explained.

In addition, HTML is the universal language of the network, a simple and universal integrated markup language. It allows web page makers to create complex pages that combine text and pictures, and these pages can be viewed by anyone else on the Internet, no matter what type of computer or browser they use. Isn't it amazing? It's not amazing at all, because what you are seeing now is a page written in this language. Ha ha.

Maybe you have heard of many softwares that can edit web pages. In fact, you don't need any special software to create HTML pages. All you need is a word processor (such as McrosoftWord\ Notepad \ Wordpad, etc. ) and working knowledge of HTML. In fact, you will soon find that the basic HTML language is easy to die out.

HTML is just a series of tags combined into a text file. They are the conductor of the band, telling the musicians where to pause and where to get excited.

HTML tags are usually full names (such as blockquote) or abbreviations of English words (such as "p" for Paragragh), but they are different from ordinary text because they are placed in a single book title. Therefore, the Paragragh tag is

As for labels, it is important to remember that they come in pairs. Whenever a tag is used-for example

Basic HTML pages are downloaded from

Title words-sandwiched in the middle

Then let's build a simple example, which is very simple. Of course, the first step is to create a new text file (remember, if you use a complex word processor, you should save it in "plain text" or "plain text") and name it "xxxx.html". Call it whatever you want, but remember, use English.

Then open it with a browser, and you will see the simplest self-made page.

(XHTML 2.0, W3C working draft)

There was no 1.0 version of HTML because there were many different versions at that time. Some people think that Tim Berners Lee's version should be regarded as the first edition, which has no IMG element. At that time, the development of the subsequent version named HTML+ started at 1993, and was originally designed as "a superset of HTML". The first formal specification used 2.0 as its version number to distinguish it from various HTML standards at that time. The development of HTML+ continues, but it has never become a standard.

HTML3.0 specification was put forward by W3C in March 1995, which provides many new features, such as tables, text wrapping and the display of complex mathematical elements. Although it was designed to be compatible with version 2.0, it was too complicated to realize this standard at that time. When the draft expired in September, 1995, the development of the standard was stopped due to the lack of browser support. 3. The version of1has never been formally proposed. The next version is to develop HTML 3.2 code-named Wilbur, which removes most of the new features in 3.0, but adds many browser-specific elements and attributes, such as Netscape and Mosaic. HTML's support for mathematical formulas eventually became another standard MathML.

HTML 4.0 has also added many browser-specific elements and attributes, but at the same time, it has begun to "clean up" this standard, marking some elements and attributes as obsolete, and it is recommended not to use them again. The future of HTML will be better combined with CSS.
