＜style lang=“scss“ scoped＞对elementui内置的类名无效

<el-descriptions class="desc"><el-descriptions-item label="审核状态"><span v-if="basicValue.status<=1">未完成</span><span v-if="basicValue.status === 2">待审核</span><span v-if="basicValue.status === 11">未通过</span><span v-if="basicValue.status === 12">已通过</span></el-descriptions-item>
</el-descriptions>

此时要设置el-descriptions-item__label（审核状态）的样式，html没有直接的class=“el-descriptions-item__label”

无效写法：

<style lang="scss" scoped>.desc{
    .el-descriptions-item__label{
     //无效font-size: 20px;}}
</style>

有效写法：

<style lang="scss" scoped>::v-deep .desc{
    .el-descriptions-item__label{
     //有效font-size: 20px;}}
</style>

重点：
::v-deep
