配置好Sublime和插件之后,可以学习具体的Html的标签知识点了。这部分只是知识点,记忆就好。
-----------------------------------
先来点儿技巧
Tips1:在html格式文件首行,输入“html:5”后,按Tab键,自动出现H5版本的模板,很方便哦!如下图:
新项目直接使用HTML5标准,像4s 4t xs都过时了。
-------------------------------------------------------------
Tip2:快速批量注释ctrl/cmd + “/”。
--------------------------------------------------------------------------------
Tips3:快速复制本行 ctrl+shift+D
--------------------------------------------------------------------------------
Tips4:快速生成标签:h1+Tab,p + Tab 等
-----------
那些标签们
1、标签
属性1:lang:语言,en代表英文,影响seo。
<html lang="en">
2、
为了浏览器设置,不展示信息。
编码格式:
3.可以避免浏览器解析乱码。
<meta charset="UTF-8"><br />
关于编码:utf-8是最全的编码格式。
4. 页签标题,影响网站seo。
5.作用
1dns预解析,2引入网站icon图标,3引入css样式。
6.标题标签
一个页面中最好一个。利于seo。
<body> <h1 id="one">one</h1> <h1 id="one">one</h1> <h2 id="two">two</h2> <h1 id="one">one</h1> <h1 id="one">one</h1></body>
7.
段落标签。
自用一行,不与其他段落共用一行。还有段间距。如图所示:
8、
水平线
属于单标签,不用斜线闭合。
<h1 id="one">one</h1> <hr> <p>this is a paragraph.this is a paragraph.this is a paragraph.this is a paragraph.this is a paragraph.</p>
9、
强制换行标签
(因为html中自带空格回车合并功能),br功效等于回车键。
10、  强制空格,等于空格一次。
11、行内文本节标签
可以在任何地方,用途:方便进行css处理。
<p>this is a paragraph. <span>span1</span> <span>span2</span> this is a paragraph.this is a paragraph.this is a paragraph.this is a paragraph.</p>
12、定义着重文字的标签,注:并不一定是斜体!
<p>this is a paragraph.this is a <em>important</em> paragraph.this is a paragraph.this is a paragraph.this is a paragraph.</p>
其中important被强调,利于seo。
13、定义斜体字标签(不推荐,css就够了)
第一讲先到这里,洗洗睡吧~

HTML, CSS and JavaScript are the core technologies for building modern web pages: 1. HTML defines the web page structure, 2. CSS is responsible for the appearance of the web page, 3. JavaScript provides web page dynamics and interactivity, and they work together to create a website with a good user experience.

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.
