vue公共样式代码存放在/src/styles文件夹里

index里引入其他组件公共样式，index.scss文件内容如下：

@import './sidebar.scss';
@import './searchForm.scss';body {height: 100%;-moz-osx-font-smoothing: grayscale;-webkit-font-smoothing: antialiased;text-rendering: optimizeLegibility;font-family: Helvetica Neue, Helvetica, PingFang SC, Hiragino Sans GB, Microsoft YaHei, Arial, sans-serif;margin: 0;
}
body ::-webkit-scrollbar {width: 9px;height: 13px;left: 8px;overflow: auto;
}
body ::-webkit-scrollbar-thumb {border-radius: 10px;background-color: #b6b6b6;
}

在main.js中引入index

import '@/styles/index.scss';
