vant 使用deep修改样式不好使解决方案

<template>
  <div class="box"></div>
</template>
 
import { Toast } from "vant";
Toast.setDefaultOptions({ teleport: ".box" });
 
<style lang="scss" scoped>
	:deep(.van-toast) {
      width: auto;
      padding: 30px;
      font-size: 32px;
      width: 100vw;
    }
</style>
