The three core standards of the Web usually refer to:

1. HTML (Hypertext Markup Language): HTML is the basis of the Web, which provides a standard way to create and describe the content of Web pages. Tags and attributes are used in HTML to define various elements on the page, such as titles, paragraphs, images, links, etc. The continuous development and updating of HTML standards enables Web pages to support increasingly rich content and interaction methods.

2. CSS (Cascading Style Sheets): CSS provides a standard way to define the style and layout of a Web page. CSS can control all aspects of style such as color, font, size, spacing, background, etc. on the page. It can also implement layout control and responsive design. CSS allows web designers to separate style and content, making pages easier to maintain and modify.

3. JavaScript: JavaScript is a scripting language that can add dynamic effects and interactive features to Web pages. JavaScript can monitor user actions, handle input, output, and page events, and dynamically change the content and behavior of the page. JavaScript can also interact with back-end servers to transfer and process data. The advent of JavaScript has made web applications more powerful and flexible.

These three standards together form the foundation of modern web development, and they provide strong support for the implementation and development of web applications. At the same time, with the continuous development of Web technology, many other development standards and technologies have emerged, such as AJAX, RESTful API, responsive design, etc. The continuous improvement and updating of these technologies have continuously improved the functions and experience of the Web. .
