CSS中使用text-align、margin：0 auto居中的示例代码

<template>
  <div class="father">
    <div>
      <img src="~@/assets/img/rules-detail-no-record.png">
      <span>我是内层div内容</span>
    </div>
    <span>我是外层div内容</span>
    <div class="bg"></div>
  </div>
</template>

<script>
export default {
  name: "test"
}
</script>

<style scoped>
.father{ //使被其包围的内联元素居中

  background: #2e90fc;
  text-align: center;
}
.bg{ //块元素居中
  background: #fc2e80;
  width: 60px;
  height: 60px;
  margin: 0 auto;
}
</style>
