题外话
传统的开发我们是在编辑器操作代码保存,再到浏览器预览查看效果的;
而如今的firebug和chrome的内置调试器就不需要了..可以直接实时编辑且看到效果;
在调试中对代码的操作不会保存到本地实际代码中..是不是很赞!!;
- 进入调试工具界面,按下”瓢虫”旁边的小鼠标,再进行网页元素的选择
- 默认快捷键,Ctrl + shift + C
- 鼠标移动到网页的某一块元素,鼠标右键,使用Firebug查看元素
##HTML元素编辑
除了写死的代码结构不能操作外(比如DIV块标签),内部的各种属性和内容都支持实时修改和预览的;
修改其中内容,只要单击你选中的东东即可,会有一个小小的蓝色框框出来
比如:
HTML DOM选定
可以轻而易举的选定各种包裹层和父类,单击即可
CSS元素编辑(实时预览)
CSS像素微调技巧
CSDN不支持GIF动态图..所以没做…..百看不如一试
概览区域
全局自定义快捷键调用: ctrl+shift+alt+b,当然也可以点击”瓢虫进去”
Firebug全局快捷键,支持自定义
哪个和你的习惯冲突了.修改内部快捷键保存确定即可生效

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.
