Container 布局容器

用于布局的容器组件，方便快速搭建页面的基本结构：

<el-container>：外层容器。当子元素中包含 <el-header> 或 <el-footer> 时，全部子元素会垂直上下排列，否则会水平左右排列。

<el-header>：顶栏容器。

<el-aside>：侧边栏容器。

<el-main>：主要区域容器。

<el-footer>：底栏容器。

以上组件采用了 flex 布局，使用前请确定目标浏览器是否兼容。此外，<el-container> 的子元素只能是后四者，后四者的父元素也只能是 <el-container>。

常见页面布局

实现代码：

<template>
<div class="common-layout">
  <el-container>
    <el-header>Header</el-header>
    <el-main>Main</el-main>
  </el-container>
  <el-container>
    <el-header>Header</el-header>
    <el-main>Main</el-main>
    <el-footer>Footer</el-footer>
  </el-container>
  <el-container>
    <el-aside width="200px">Aside</el-aside>
    <el-main>Main</el-main>
  </el-container>
  <el-container>
    <el-header>Header</el-header>
    <el-container>
      <el-aside width="200px">Aside</el-aside>
      <el-main>Main</el-main>
    </el-container>
  </el-container>
  <el-container>
    <el-header>Header</el-header>
    <el-container>
      <el-aside width="200px">Aside</el-aside>
      <el-container>
        <el-main>Main</el-main>
        <el-footer>Footer</el-footer>
      </el-container>
    </el-container>
  </el-container>
  <el-container>
    <el-aside width="200px">Aside</el-aside>
    <el-container>
      <el-header>Header</el-header>
      <el-main>Main</el-main>
    </el-container>
  </el-container>
  <el-container>
    <el-aside width="200px">Aside</el-aside>
    <el-container>
      <el-header>Header</el-header>
      <el-main>Main</el-main>
      <el-footer>Footer</el-footer>
    </el-container>
  </el-container>
</div>
</template>
<script>
</script>
<style>
.el-header,
  .el-footer {
    background-color: #b3c0d1;
    color: var(--el-text-color-primary);
    text-align: center;

    color: var(--el-text-color-primary);
    text-align: center;
    line-height: 160px;
  }
  body > .el-container {
    margin-bottom: 40px;
  }
  .el-container:nth-child(5) .el-aside,
  .el-container:nth-child(6) .el-aside {
    line-height: 260px;
  }
  .el-container:nth-child(7) .el-aside {
    line-height: 320px;
