What technologies constitute web standards?

Web standards include HTML, CSS, JavaScript, DOM, XML, XHTML, HTTP, W3C, ARIA, SEO and other technologies. Detailed introduction: 1. HTML, the basic language used to create the structure of web pages; 2. CSS, used to control the appearance and style of web pages; 3. JavaScript, used to add interactivity and dynamic functions to web pages; 4. DOM, based on hierarchy The structural method represents the API of the HTML document; 5. XML, the markup language used to describe the data structure, etc.

Web standards are a set of technical specifications and guidelines designed to ensure the accessibility, usability, and interoperability of web pages. Here are some of the important technologies that make up web standards:

HTML (Hypertext Markup Language): HTML is the basic language used to create the structure of web pages. It defines the various elements of web content (such as titles, paragraphs, images, etc.) and the relationships between them.

CSS (Cascading Style Sheets): CSS is used to control the appearance and style of web pages. It describes how to render HTML elements through a series of rules and attributes, including fonts, colors, layout and animation effects, etc.

JavaScript: JavaScript is a scripting language used to add interactivity and dynamic functionality to web pages. It can be used with HTML and CSS to implement form validation, user input processing, dynamic content loading and other functions.

DOM (Document Object Model): DOM is an API that represents HTML documents in a hierarchical manner. It allows JavaScript to change the structure, style and content of web pages by manipulating DOM elements.

XML (Extensible Markup Language): XML is a markup language used to describe data structures. It serves as a data exchange format to transfer and share data between different platforms and applications.

XHTML (Extensible Hypertext Markup Language): XHTML is a combination of HTML and XML, it is a stricter version of HTML. XHTML uses the syntax rules of XML to make web pages easier to process and parse.

HTTP (Hypertext Transfer Protocol): HTTP is the basic protocol for Web communication and is used to transfer HTML, CSS, JavaScript and other resources between clients and servers. It defines the format and behavior of requests and responses.

W3C (World Wide Web Consortium) standards: W3C is an international standardization organization dedicated to formulating and promoting Web technology standards. It formulates core specifications for HTML, CSS, DOM, etc., and provides testing tools and guidelines to help developers follow these standards.

ARIA (Accessibility Rich Internet Applications): ARIA is a set of technical specifications for enhancing the accessibility of web applications. It provides properties and roles that allow screen readers and other assistive technologies to better understand and interact with web content.

SEO (Search Engine Optimization): SEO is a set of techniques and strategies designed to improve a website’s ranking in search engine results pages. It involves optimizing aspects such as web page structure, content, and links to improve the visibility and accessibility of the website to search engines.

These technologies form the basis of Web standards. By following these standards, developers can create more stable, reliable and accessible web pages. At the same time, web standards also help achieve better interoperability between different devices and different platforms and provide a consistent user experience.
