1. 注释
HTML中的注释和其它语言注释作用相似,都是为了方便阅读和调试代码。当浏览器遇到注释时会自动忽略注释内容。HTML的注释格式多行和单行注释都用一种格式,如下:
当页面HTML结构复杂或内容较多时,需要添加必要的注释来方便阅读和维护代码。同时,有时候为了调试代码,需要暂时注释掉一些不必要的代码,方便调试。
代码规范:需要注意的是,XHTML 1.0标准规定不要在注释中在出现双横线"--".
不规范的注释:

2. 保留字符
因为大于号(>)小于号(<)等符号以作为HTML的语法符号,所以,如果要在页面中显示这些特殊符号,就必须使用相应的HTML的代码表示,这些特殊符号对应的HTML代码称为字符实体。
常用的特殊符号和对应的字符实体表,这些字符实体都是以"&"开头,以英文分号";"结束。

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

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 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.
