The three major standards of w3c are HTML, CSS and JavaScript. Detailed introduction: 1. HTML is a markup language used to create Web pages. It defines the structure and content of Web pages. Its standards stipulate the semantics and usage of various elements in Web pages, such as titles, paragraphs, links, pictures, etc., It provides a wealth of tags and attributes, allowing developers to create well-structured and semantically clear Web pages; 2. CSS is a style sheet language used to control the style of Web pages, defining the appearance and layout of Web pages, etc.

W3C (World Wide Web Consortium) is an international standardization organization dedicated to promoting and formulating standards for Web technology. Its work mainly includes developing Web standards, promoting Web technologies and providing relevant guidance and resources. The three major standards of W3C are:
1. HTML (Hypertext Markup Language): HTML is a markup language used to create Web pages and defines the structure and content of Web pages. W3C has developed a series of HTML specifications, including HTML4, XHTML1 and HTML5. HTML standards specify the semantics and usage of various elements in Web pages, such as titles, paragraphs, links, pictures, etc. It provides rich tags and attributes, allowing developers to create well-structured and semantically clear Web pages.
2. CSS (Cascading Style Sheets): CSS is a style sheet language used to control the style of Web pages, defining the appearance and layout of Web pages. W3C has developed a series of CSS specifications, including CSS1, CSS2 and CSS3. CSS standards specify how to select and style elements in web pages, such as fonts, colors, backgrounds, layouts, etc. It provides a rich set of selectors and attributes, allowing developers to have precise style control over Web pages.
3. JavaScript: JavaScript is a scripting language used to add interactive and dynamic effects to web pages. Although JavaScript is not a W3C standard, the W3C has standardized JavaScript through the ECMAScript specification. ECMAScript defines the core syntax and features of JavaScript, such as variables, functions, objects, arrays, etc. W3C has also developed a series of JavaScript-related standards, such as DOM (Document Object Model) and XMLHttpRequest, etc., for operating and processing elements and data in Web pages.
These three major standards together form the basis of Web development. They cooperate with each other to enable Web pages to have multiple functions such as structure, style, and interaction. HTML is responsible for describing the structure and content of the page, CSS is responsible for controlling the appearance and layout of the page, and JavaScript is responsible for realizing the interactive and dynamic effects of the page. This division of labor makes Web development more modular and flexible, allowing developers to better organize and manage Web projects and provide better user experience and maintainability.
In addition to these three major standards, W3C has also formulated some other important standards, such as XML (eXtensible Markup Language), SVG (Scalable Vector Graphics) and Web Accessibility. These standards have played an important role in the development and development of Web technology. Played an important role in promotion. W3C is not only committed to formulating standards, but also actively promotes the implementation and popularization of standards, provides support and guidance to developers through official documents, sample codes, testing tools, etc., and promotes the progress and development of Web technology.
