 ## Positioning and Goals of antd-style
 
-Therefore, when we cleanly separate the above two, it becomes very clear: the positioning of `antd-style` is a `style practice` library, providing a set of deterministic style writing solutions for antd's developer users, and providing best practice solutions for the vast majority of style writing scenarios, including but not limited to: 1) application styles, 2) component styles, 3) less migration, 4) responsive design, 4) dynamic themes, 5) custom themes, 6) token extension, 7) design collaboration, and so on.

 Therefore, antd-style will encapsulate a set of APIs on top of excellent CSSinJS style engines in the community, providing application developers and component developers with a more user-friendly syntax and better performance.

-因此,将上述两者切割干净后会就会非常清晰： `antd-style` 的定位就是一个 `样式实践` 库，为 antd 的开发者用户提供一套具有确定性的样式书写方案，并在绝大部分样式书写场景都提供了最佳实践的方案：包括但不限：1）应用样式、2）组件样式、3）less 迁移、4）响应式、4）动态主题、5）自定义主题、6）token 扩展、7）设计协同等等。

 所以，antd-style 会在社区优秀的 cssinjs 样式引擎上层封装出一套 api，为应用开发者、组件开发者提供更加易写的语法，且能获得更优的性能。
