What is the correct way to implement ::v-deep(<inner-selector>) in a Vue component?

I am attempting to assign an existing style class to a child element that will be loaded using the v-html directive. Since /deep/ and >>> are no longer supported, I have tried using ::v-deep in Vue.

<template>
<div v-else v-html="childHtml" class="parent-class"></div>
</template>

<style scoped>
.parent-class ::v-deep .child-class {
  border: unset;
  border-radius: 2px;
  margin: 0 auto;
  margin-bottom: 2%;
  background-color: #fff;
  box-sizing: border-box;
  zoom: 70%;
}
</style>

However, the Vue compiler is giving me an error message stating that *::v-deep usage as a combinator has been deprecated. It suggests to use ::v-deep() instead (using Vue 3.0.0-beta.1).

Can anyone please advise on how to properly use ::v-deep() and resolve this compilation error?

Your assistance is greatly appreciated. Thank you in advance.

Answer №1

If you are not using sass/scss, consider trying out the

>>> .class-i-want-deep{ /// }
method as an alternative. You can refer to the documentation from vue-loader here. Regarding the error message, it mentions:

"*::v-deep usage as a combinator has been deprecated. Use ::v-deep() instead. (using Vue 3.0.0-beta.1)"

It seems that the syntax for ::v-deep() is no longer supported in Vue 3. Consider using the new ::v-deep(), although specific documentation for this update may be scarce. Update: It appears that OP has reported successful usage of ::v-deep() with version 3.0. I have yet to confirm this personally.
