1、新建theme.scss文件

// 主题1
$background-color-black: #0D2865;
$background-color-white: #eba5a5;
$font-color-white: #f1ff77;
$font-color-black: #ea4141;
// 主题2
$background2-color-black: #75084f;
$background2-color-white: #998a00;
$font2-color-white: #1e3dea;
$font2-color-black: #ffffff;

2、新建mixin.scss文件，进行主题封装

@import './theme.scss';
@mixin bg_color($color) {
  background-color: $color;
  [data-theme="black"] & {
    background-color: $background-color-black;
  }
  [data-theme="white"] & {
    background-color: $background-color-white;
  }
}
@mixin font_color($color) {
  color: $color;
  [data-theme="black"] & {
    color: $font-color-black;
  }
  [data-theme="white"] & {
    color: $font-color-white;
  }
}
@mixin bg2_color($color) {
  background-color: $color;
  [data-theme="black"] & {
    background-color: $background2-color-black;
  }
  [data-theme="white"] & {
    background-color: $background2-color-white;
  }
}
@mixin font2_color($color) {
  color: $color;
  [data-theme="black"] & {
    color: $font2-color-black;
  }
  [data-theme="white"] & {
    color: $font2-color-white;
  }
}

3、操作展示文件test.vue

<template>
  <div class="about">
    <button @click="toggoleTheme">点击变色</button>
    <div class="changebox">这是一个变色盒子</div>
    <div class="changebox2">这是一个变色盒子2</div>
  </div>
</template>
<script>
export default {
  data() {
    return {
      theme: 'black'
    }
  },
  methods: {
    // 当前分为white主题和black主题进行切换 
    toggoleTheme() {
      this.theme = this.theme === 'white' ? 'black' : 'white'
    // 通过setAttribute设置data-theme主题进行切换
      document.documentElement.setAttribute('data-theme', this.theme );
    }
  }
}
</script>
<style lang="scss">
@import '@/assets/mixin.scss';
.changebox {
  width: 200px;
  height: 200px;
  @include bg_color($background-color-black);
  @include font_color($font_color-black);
}
.changebox2 {
  width: 200px;
  height: 200px;
  @include bg2_color($background2-color-black);
  @include font2_color($font2_color-black);
}
</style>
