css多次加载污染全局

页面引用样式导致 多页面共用CSS，每个页面都引入了所有css

scoped 限制样式表，仅当前页面使用

<style  scoped>
  @import "../../assets/css/ydui.min.css";
  @import "../../assets/css/yduidemo.min.css";
  @import "../../assets/css/paylogpub.min.css";
</style>
<script>
  import "../../assets/css/ydui.min.css";
  import "../../assets/css/yduidemo.min.css";
  import "../../assets/css/paylogpub.min.css";
</script>
