Chinese-English Translation:

CSS3是CSS(层叠样式表)技术的升级版本,于1999年开始制订,2001年5月23日W3C完成了CSS3的工作草案,主要包括盒子模型、列表模块、超链接方式、语言模块、背景和边框、文字特效、多栏布局等模块 。

CSS3 is an upgraded version of CSS (cascading style sheet) technology, which was formulated in 1999. On May 23, 2001, W3C completed the working draft of CSS3, mainly including box model, list module, hyperlink mode, language module, background and frame, text effect, multi column layout and other modules.

CSS 演进的一个主要变化就是 W3C 决定将 CSS3 分成一系列模块。浏览器厂商按 CSS 节奏快速创新,因此通过采用模块方法,CSS3 规范里的元素能以不同速度向前发展,因为不同的浏览器厂商只支持给定特性。但不同浏览器在不同时间支持不同特性,这也让跨浏览器开发变得复杂 。

A major change in CSS evolution is the W3C’s decision to break CSS3 into a series of modules. Browser manufacturers innovate rapidly according to the rhythm of CSS, so by adopting the module method, the elements in CSS3 specification can develop at different speeds, because different browser manufacturers only support given features. But different browsers support different features at different times, which also complicates cross browser development.

早在 2001 年 W3C 就完成了 CSS3 的草案规范。CSS3 规范的一个新特点是被分为若干个相互独立的模块。一方面分成若干较小的模块较利于规范及时更新和发布,及时调整模块的内容,这些模块独立实现和发布,也为日后 CSS 的扩展奠定了基础。另外一方面,由于受支持设备和浏览器厂商的限制,没备或者厂商可以有选择的支持一部分模块,支持 CSS3 的一个子集,这样有利于 CSS3 的推广 。

As early as 2001, W3C completed the draft specification of CSS3. A new feature of CSS3 specification is that it is divided into several independent modules. On the one hand, it is better to divide into several smaller modules to update and release the specification in time and adjust the content of the modules in time. These modules can be implemented and released independently, which also lays a foundation for the future expansion of CSS. On the other hand, due to the limitations of supported devices and browser manufacturers, some modules and a subset of CSS3 can be supported if they are not prepared or the manufacturers have the choice, which is conducive to the promotion of CSS3.

CSS3 编程工具同 CSS,任何一种文本编辑工具都可用来编写,如:Windows 下的写字本、记事本;或其他专门用于编辑网页文本的工具 ,如:IntelliJ IDEA、Eclipse、MyEclipse、webstorm、sublime text;此外还有专门针对前端开发的插件,如:Emmet。

CSS3 programming tool is the same as CSS, any text editing tool can be used to write, such as: Notepad under windows; or other tools specially used to edit web page text, such as: IntelliJ idea, eclipse, MyEclipse, webstorm, sublime text; in addition, there are plug-ins specially developed for front-end, such as Emmet.

CSS3 原理同 CSS,是在网页中自定义样式表的选择符,然后在网页中大量引用这些选择符 。

The principle of CSS3 is the same as that of CSS, which is to customize the selectors of style sheets in web pages, and then reference these selectors in web pages.
