vue3修改elemeng-plus样式，报错 ::v-deep usage as a combinator has been deprecated. Use :deep(<inner-sele
.el-header{ border-bottom: 1px solid #ddd; }
换成
::v-deep(.el-header){ border-bottom: 1px solid #ddd; }
.el-header{ border-bottom: 1px solid #ddd; }
换成
::v-deep(.el-header){ border-bottom: 1px solid #ddd; }
