vue3 less 的使用 手写header/context/menu 组件

配置好reset后

vue3 项目使用自己的reset.less 配置，重置自带样式_安果移不动的博客-CSDN博客

效果

按照层级新建如下四个Index.vue文件

 也很好弄

下文叙述中将  Content下的Index.vue 简称 Content

<template>
  <div class="content"> 内容区域

    <div :key="item" v-for="item in 100" class="content-items">{
   
   { item }}</div>
  </div>
</template>

<script setup lang="ts">

</script>

<style lang="less" scoped>

.content {
  flex: 1;
  margin: 20px;
  border: 1px solid #ccc;
  overflow: auto;

  &-items {
    padding: 20px;
    border: 1px solid #ccc;
  }
}
</style>

Header

<template>
  <div class="header"> 头部区域</div>
</template>

<script setup lang="ts">

</script>

<style lang="less" scoped>
.header {
  height: 60px;
  border-bottom: 1px solid #ccc;
}
</style>

Menu

<template>
  <div class="menu"> 菜单区域</div>
</template>

<script setup lang="ts">

</script>

<style lang="less" scoped>
.menu {
  width: 200px;
  border-right: 1px solid #ccc;
}
</style>

layout

<template>
  <div class="layout">
    <Menu></Menu>
    <div class="layout-right">
      <Header></Header>
      <MyContent></MyContent>
    </div>
  </div>
</template>

<script setup lang="ts">
import Menu from "@/layout/Menu/Index.vue";
import Header from "@/layout/Header/Index.vue";
import MyContent from "@/layout/Content/Index.vue";


</script>

<style lang="less" scoped>
.layout {
  display: flex;
  height: 100%;
  overflow: hidden;
  //子级的右边 这个是可好玩的语法
  &-right {
    flex: 1;
    display: flex;
    flex-direction: column;

  }
}

</style>

App.vue

<template>
  <Layout/>
</template>

<script setup lang="ts">
import Layout from "@/layout/Index.vue";


</script>

<style lang="less">
html, body, #app {
  height: 100%;
  overflow: hidden;
}

</style>

less相较于css新的知识点不多就有一个

&-子组件的剩余id

如

这种写法很潮流，我第一次遇到。。。。
