使用Element（2.13.1版本）的Container布局容器布局，按照官网的代码运行后不能撑开整个页面，只能显示一段高度，代码如下：
<el-container>
<el-header>Header</el-header>
<el-container>
<el-aside width="210px">
left
</el-aside>
<el-main>Main</el-main>
</el-container>
</el-container>
那如何让它高度百分百显示呢？
给html、body、#app及最外层.el-container的height设置100%即可。
index.html：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width,initial-scale=1.0"> <title>demo1</title> <style> html, body { margin: 0; height: 100%; } </style> </head> <body> <div id="app"></div> <!-- built files will be auto injected --> </body> </html>app.vue：
<template>
<div id="app">
<el-container style="height: 100%;">
<el-header>Header</el-header>
<el-container>
<el-aside width="210px">
left
</el-aside>
<el-main>Main</el-main>
</el-container>
</el-container>
</div>
</template>
<script>
export default {
name: "App",
components: {
}
};
</script>
<style>
#app {
font-family: "Avenir", Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
color: #2c3e50;
height: 100%;
}
.el-header,
.el-footer {
background-color: #b3c0d1;
color: #333;
line-height: 80px;
}
.el-aside {
background-color: #d3dce6;
color: #333;
}
.el-main {
background-color: #e9eef3;
color: #333;
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;
}
</style>
