【经典】全局公共scss文件的引入使用

1、在src/css/创建_common.scss，不要问为什么用下划线开头，自己去百度（SASS会通过这些下划线来辨别哪些文件是SASS片段，并且不让片段内容直接生成为CSS文件，从而只是在使用@import指令的位置被导入）

2、在vue文件中引入scss使用（也不要问为什么import的时候没有下划线了，去百度）

<style lang='scss' scoped>
    @import "~@/css/common";

    body{
        @extend %transitionAll;
        //诸如此类巴拉巴拉……
    }
</style>
