In previous tutorials of Script House, we have repeatedly emphasized making web page HTML files semantic. We should choose the most appropriate HTML or XHTML tags based on the structure of the web page's HTML document, rather than selecting them based on their appearance. Use the P tag to define a paragraph rather than using it to get a line break effect. We use h1-h6 tags to mark headings, rather than using them to achieve text size and bold effects.
For example, a title, we can use h1 to define it:
The title text of the article is written here
rather than using any other way to define it:
The title text of the article is written here
In the previous article of Script House, we listed all the tags allowed by XHTML1.0. We can also find that there are actually very few element tags that we can choose. But we also clearly realize that these refined element marks also have clearer meanings. If you really can't find the right element to tag, you can use the generic div and span tags.
The use of div and span tags on the page is a new problem, and we are prone to using them too much. Necessary and reasonable use of divs can significantly enhance the structure of the document. If you look at your HTML document and find that there are a lot of divs and spans, then you have to look at the problem from a different perspective. Is there abuse? Are there better markers to replace them? If h1 can better represent the marked content, then you have to give up p or span to define it.
Perhaps this is a contradiction, and it is difficult for us to grasp how to use them correctly, or perhaps we cannot get a clear answer at all. But one thing needs to be clarified, we should make the document have a clear logical structure and make it easier to apply styles. We can think of div as just a container, or a "part" of the document. We use too many containers, which is not a wise pattern. And a container that is just right and in a reasonable position can make the entire document appear organized.
The following code is more reasonable and effective:

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.
