W3C Tutorial (2): W3C Program_HTML/Xhtml_Web Page Production
The W3C's standardization process is divided into 7 different steps.
The W3C’s standardization process is divided into 7 distinct steps. Approval steps for W3C specifications
In the process of W3C publishing a new standard, the specification is gradually established from a simple idea to a recommended standard through the following rigorous process: W3C receives a submission Publish a record by W3C Create a working group by W3C Published a working draft by W3C Publish a candidate recommendation by W3C Publish a proposed recommendation by W3C Recommended by W3C
The following chapters of this tutorial summarize the corresponding activities of HTML, CSS, XML, and XSL at W3C, including the status and timeline of each web standard. W3C Submissions
Any W3C member can submit a proposal (proposal) to the consortium that they hope will become a Web standard. Most W3C recommendations originate from a submission to the consortium.
If a submission is within the W3C's work area (or charter), the W3C will decide whether to initiate improvements to the proposal. W3C Notes
Typically, a submission to the W3C becomes a record. A record is a description of a proposal distilled as a public document.
W3C only logs user discussions. Publication of a record does not constitute endorsement thereof. The content of a record is edited by the member who submitted the record, not by W3C. Records can be updated, replaced or discarded at any time. The publication of a record also does not indicate that the W3C has initiated any work related to this record. W3C Working Groups
When a submission is recognized by the W3C, a working group is formed that includes members and other interested parties.
Working groups typically define a timeline and publish a working draft of the proposed standard. W3C Working Drafts
W3C working drafts are typically posted on the W3C website, along with an invitation for public annotation.
Working drafts describe work in progress but should not be used as any reference material. Its content may be updated, replaced or discarded at any time. W3C Candidate Recommendations
Some specifications will be more complex than others and may require more funding, more time, and more testing from members and software developers. Sometimes these specifications are published as candidate recommendations.
Candidate recommendations are also a "work in progress" and should not be used as reference material. This document may be updated, replaced or obsoleted at any time. W3C Proposed Recommendations
Proposed recommendations represent the final stage of work in the working group.
Proposing recommendations is also a "work in progress". This document may be updated, replaced or obsoleted at any time. But even though it does not imply any official endorsement by the W3C, in many cases the proposed recommendation is close to the final recommendation in both content and timing. W3C Recommendations
W3C recommendations have been reviewed by W3C members and formally approved by the W3C Director.
W3C Recommendations are stable documents and can be used as reference materials.

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.
