variable.scss：scss的全局变量

// 配置scss全局变量
$color:red

在mian.ts文件引入scss

import '@/styles/index.scss'

配置vite.config.ts文件

export default defineConfig({
  plugins: [
    vue()
  ],
  // scss全局变量配置
  css: {
    preprocessorOptions: {
      scss: {
        javascriptEnable: true,
        additionalData: '@import "./src/styles/variable.scss";'
      }
    }
  }
})

案例代码

<template>
  <div><h1>测试代码</h1></div>
</template>

<script setup lang="ts"></script>

<style scoped lang="scss">
div {
  h1 {
    color: $color;
  }
}
</style>

由于引入了reset.scss清除样式，所以就没有h1的效果了，可以把reset.scss样式去掉感受效果
$color就是variable.scss中配置的全局变量
