但是不影响浏览器效果，也不报错
<style lang="stylus" scoped > article display flex background lightblue height 0.64rem//此处数字处 .left float left .center flex 1//此处数字处 background white .right float right </style>
1.
style默认的css
类似于script默认的 javascript一样
<script type="text/javascript"></script>
<script></script>
解决；我们要修改默认语言
<style lang="stylus" scoped type="text/stylus"> //加一行即可 article display flex background lightblue height 0.64rem .left float left .center flex 1 background white .right float right </style>
