代码教學

本工具[在线CSS美化(格式化)/加密/解密/混淆]依赖于Codemirror,它的Github地址为：https://github.com/codemirror/CodeMirror, 加密、解密使用到http://dean.edwards.name/packer/ 库,美化使用到csso-browser库，https://github.com/css/csso   。使用代码如下

STEP 1

STEP 2

核心代码如下

},

值得一試的三個理由：

1. 整合各種程序员开发中经常使用的开发测试工具。

2. 简洁美观大气的网站页面

3. 支持 在线格式化执行代码、APK在线反编译、在线高强度密码生成、在线网页截图 等二十多種工具服务

4. 同时还推荐一下它的姐妹网 www.videofk.com 视频下载工具箱
