## 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。
|
||
|
||
:::tip
|
||
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>`。
