-## Wkit
+## 百搭UI组件库的核心
-> 一个简单易用、功能完善的用于开发`web components`的轻量级开发库。模板解析基于`lit-html`二次开发

 ### 开发文档

+[开发文档](https://github.com/bd-js/core/wiki)
 
 
 ### 我们的特色
 
 - `@xxx=yyy` 事件绑定, 可以任意节点上直接使用类似`vue事件绑定`的这种写法, 就可实现事件绑定。组件被移出文档时, 事件会**自动销毁**, 无须手动销毁。
-- `@click.stop=xxx` 事件绑定支持修饰符
 - `:xxx=yyy`, 属性绑定, 类似`vue`,在属性前加上`:`, 该属性不再使用`setAttribute()`, 而是直接赋值, 可满足你需要传递复杂数据结构的需求。
 - `#animation={type}`, 开箱即用的动画配置, 内置6种动画`fade(默认), scale, bounce, micro-bounce, rotate, slide`
 - `ref=xxx`, 类似`vue`的节点标识, 可方便的在`mounted()`之后通过 `this.$refs.xxx` 来访问该节点
-- 内置特色的双向绑定方法`live()`
 - 用内置的`bind()`方法来给当前组件绑定事件时, 组件移除时事件也会自动销毁,无需手动销毁。
 - 灵活的`props`定义
