What is html? Introduction to html

HTML, the full name of "HyperText Markup Language", is a markup language used to create web pages. Its main purpose is to convey some structured information to the browser, and then let the browser render the layout, appearance and interaction of the page based on this information. HTML markup is composed of a series of tags, each tag is represented by a pair of angle brackets.

HTML was invented by European physicist Tim Berners-Lee with the original intention of helping scientific researchers share documents and knowledge. At that time, the most popular text processing software was Microsoft Word, but the documents they generated were binary documents, which were inconvenient to share and read. The advantage of HTML is that it is simple to create, easy to read, and can be easily opened on different platforms and browsers, making it the basic language of the Internet.

HTML is a text file composed of tags. Tags have certain grammatical formats and are used to contain text, images, audio, video and other content that need to be presented. The first version of HTML was released in 1990. Since then, HTML has gradually evolved into multiple versions and introduced many new features and markup language elements. New versions of HTML are released continuously and develop very quickly. The latest version is HTML5 and its subsequent standards. They not only support the latest web technology, but also have high cross-platform and cross-device compatibility.

HTML has its own specific format, and its hierarchical structure is very clear. The main parts include doctype, html, head and body. The doctype specifies the document type, the html tag is the head, the head tag is used to contain necessary information, such as style sheets and scripts, etc., and the body tag is the main body of the document, including all content presented to the browser.

The main feature of HTML is that it is easy to learn and use. Because the HTML language is an interpreted language, it does not need to be compiled into machine code, but is processed directly by the browser. Developers can create HTML files using any text editor and just need to follow some basic conventions and syntax.

In short, HTML is a markup language used to describe the structure and content of web pages, and is an important part of the foundation of the Internet. Through the continuous development of web technologies such as HTML, CSS and JavaScript, developers can create richer and more complex web pages and support more efficient interactions.
