Vue Element-Ui Container layout container

Learning vue+elementUi in the preliminary learning layout I don"t know why < el-aside > has margin

Thank you, bosses

the code is as follows: 

<template>
  <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>
</template>

<style scoped>
.el-header,
.el-footer {
  background-color: -sharpb3c0d1;
  color: -sharp333;
  text-align: center;
  line-height: 60px;
}

.el-aside {
  background-color: -sharpd3dce6;
  color: -sharp333;
  text-align: center;
  line-height: 200px;
}

.el-main {
  background-color: -sharpe9eef3;
  color: -sharp333;
  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;
}
</style>

the effect is as follows

the watch sinks. Ask the great god to explain.

introduce normalize.css

this should be provided by the browser. Under your entry page settings, margin:0

Brother, has this problem been solved?

Previous: The vue component initializes the setting content to tinymce and reports an error.

Next: Element UI Message is triggered repeatedly when both input boxes are used to check the pop-up box.
