HTML (hypertext mark-up Language), the Hypertext Markup Language or hyper-text link marking language, is the most widely used language on the Internet, and it is also the main language that makes up Web documents. The purpose of designing an HTML language is to be able to easily link text or graphics stored in one computer to text or graphics on another computer, to form an organic whole, without having to consider whether the specific information is on the current computer or on other computers on the network. We simply use the mouse to click an icon in a document, and the Internet immediately goes to the content associated with this icon, which may be stored on another computer on the network. HTML text is a descriptive text consisting of HTML commands that can describe text, graphics, animations, sounds, tables, links, and so on. The structure of HTML consists of a head, a body, two parts of the head, which describes the information required by the browser, and the body contains the specific content to be described.

In addition, HTML is the common language of the network, a simple, universal, full markup language. It allows web makers to create complex pages of text and images that can be browsed by any other person on the web, regardless of the type of computer or browser used. It's not magic at all, because now you're looking at a page written in this language!
HTML is simply a series of tags that are grouped together into a single text file. They are like the conductor of a band, telling musicians where to pause and where to be passionate.
HTML tags are usually the full name of English words (such as block references: BLOCKQUOTE) or abbreviations (such as "P" represent paragraph), but they differ from the general text because they are placed in a single title number. So the Paragragh label is <p>, and the Block reference label is <blockquote>. Some labels explain how the page is formatted (for example, start a new paragraph), others explain how the words are displayed (<b> make the text thicker) and other tags that provide information that is not displayed on the page-for example, the title.
