W3C, an organization founded in 1994, aims to unleash the full potential of the web world by promoting the development of common protocols and ensuring their universal use.
W3C, an organization founded in 1994, whose purpose is to unleash the full potential of the web world by promoting the development of common protocols and ensuring their universality. What is W3C? W3C stands for World Wide Web Consortium (World Wide Web Consortium) W3C was founded October 1994 W3C was created by Tim Berners-Lee W3C is a membership organization W3C’s job is to standardize the web W3C creates and maintains WWW Standards W3C standards are called W3C Recommendations How was the W3C created?
The World Wide Web was developed as a project of the European Organization for Nuclear Research, where Tim Berners-Lee developed the prototype of the World Wide Web.
Tim Berners-Lee - the inventor of the World Wide Web - is currently the Director of the World Wide Web Consortium.
W3C was created in 1994 to complete collaborative work between the Massachusetts Institute of Technology (MIT) and the European Research Institute for Particle Physics (CERN), with support from the U.S. Defense Advanced Research Projects Agency (DARPA) and the support of the European Commission. Standardizing the web
W3C is committed to making the web accessible to all users, regardless of literacy, ability, financial resources, or physical disabilities.
W3C also works with other standards organizations, such as the Internet Engineering Task Force, the Wireless Application Protocol (WAP), and the Unicode Consortium.
W3C is jointly operated by the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL), the European Research Consortium for Information Mathematics (ERCIM) headquartered in France, and Keio University in Japan. There are branch offices within the scope. W3C Member
Because the Web is so important (both in terms of scope and investment) that no single organization should control its future, the W3C acts as a membership organization:
Some well-known members include: IBM Microsoft America Online Apple Adobe Macromedia Sun Microsystems
W3C’s members include: software developers, content providers, enterprise users, communications companies, research institutions, research laboratories, standardization groups and governments. W3C Recommendations
The most important work of W3C is the development of Web specifications (called Recommendations), which describe the communication protocols (such as HTML and XHTML) and other building blocks of the Web.
The development of each W3C recommendation is accomplished through working groups composed of members and invited experts. The working group is funded by companies and other organizations and creates a working draft and, ultimately, a proposal recommendation. Generally, recommendations are submitted to W3C Members and Directors for formal approval.
In the next section, we will explain the specification approval process to you.

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.
