[lin52025iq]

Describe the bug

vue.config.js

module.exports = defineConfig({
    ...
    configureWebpack: {
        ...
        plugins: [
            ...
            UnpluginVueComponent({
                dts: true,
                types: [
                    {
                        from: 'vue-router',
                        names: ['RouterLink', 'RouterView']
                    }
                ],
                resolvers: [ElementPlusResolver()]
            })
        ]
    }
})

index.vue

<template>
    <div class="demo">
        <el-link type="success">click link!</el-link>
    </div>
</template>

<style>
.demo {
    width: 120px;
    height: 32px;
}
</style>

package.json

打包后得到的 css 文件

打包后的文件中包含了 el-link 的样式，但期望的应该只包含 .demo{width:120px;height:32px} 这一行样式。

其他
1: 包含的 el-link 的样式是 el-link 的所有默认样式，这会导致修改 element-plus 的变量调整的样式被覆盖。
2. 如果使用 el-input、el-button 时不会被引入额外的 el-input 的样式，但对 el-link、 el-radio、el-table 会被额外的引入样式。

因为你使用了按需引入，所以这个行为是正常行为，他会看你文件中使用了哪些组件，自动在该文件引入组件和对应样式

[loocus]

按需导入会匹配对应组件名称引入对应组件代码和样式代码，具体看完resolver就明白了

那有什么办法全局覆盖ElementPlus的样式吗
