Vue3中使用:deep修改element-plus的样式无效怎么办?
前言:当我们用 vue3 :deep() 处理 elementui 中 el-dialog_body和el-dislog__header 的时候样式一直无法生效,遇到这种情况怎么办?
解决办法:
1.直接在 dialog 上面增加class 我试过,也不起作用,最后用这种方法解决的,dialog 外面直接包一层 div
2.将样式单独写一个style标签进行覆盖---此方式由于样式写在外面,可能会影响整个项目的全局样式,--慎重考虑
需求:需要将el-drawer__header的底部的外边距去掉
方式一:
修改前:
修改后:
生效方式:1.在最外层加一层在el-dialog外面包一层
2.主要是vue3中deep会因为最外层没有根节点失效的问题,只需要加一个根节点,deep就有效了
需要注意的是 :deep(这里面只能包一个)
