使用多个卡片显示的时候，并且要求当列数到一定数目的时候，要自动换行，el-container 布局就满足了需求了，就要用到el-row 布局做分栏处理，

代码如下


<template>
 <el-row :gutter="20" class="el-row" type="flex" >
 <el-col :span="8" v-for = "(item,index) in apps" :key="item.id" class="el-col" >
  <el-card class="el-card" :key="index" onclick="">
  <div slot="header" class="clearfix">
   <span>{{item.appname}}</span>
  </div>
  <div >
   <div class="text item">
   <div class="item_tag" >
    <span >用户标签：</span>
   </div>
   <div class="item_desr">
    <span > {{item.tag}}</span>
   </div>
   </div>
   <div class="text item">
   <div class="item_tag">
    <span>搜索标签：</span>
   </div>
   <div class="item_desr">
    {{item.seatag}}
   </div>
   </div>
   <div class="text item">
   <div class="item_tag">
    <span>短信签名：</span>
   </div>
   <div class="item_desr">
    <span>
     {{item.wxname}}
    </span>
   </div>
   </div>
   <div class="text item">
   <div class="item_tag">
    <span>客服QQ：</span>
   </div>
   <div class="item_desr">
    {{item.qq}}
   </div>
   </div>
   <div class="text item">
   <div class="item_tag">
    <span>商务合作：</span>
   </div>
   <div class="item_desr">
    {{item.buscoo}}
   </div>
   </div>
  </div>
  </el-card>
 </el-col>
 <el-col :span="8">
  <el-card class="box-card" style="min-height: 200px;" align="middle" onclick="">
  <div class="el-card__body mid">
   <el-button icon="el-icon-circle-plus" circle></el-button>
   <el-button style="margin-left: 0;color: #505458" type="text">添加APP</el-button>
  </div>
  </el-card>
 </el-col>
 </el-row>
</template>
<script>

css


<style type="text/css">
 .all{
 margin-top: -30px;
 word-break: break-all;
 height: 100%;
 }
 .mid{
 margin-top: 25%;
 height: 50%;
 }
 .mid_item{
 justify-content: center;
 align-items: center;
 }
 .item {
 margin-bottom: 10px;
 }
 .item_tag{
 float:left;
 text-align:left;
 }
 .item_desr{
 margin-left: 40%;
 min-height: 30px;
 text-align:left;
 }
 .text {
 width: 100%;
 font-size: 12px;
 font-family: "Microsoft YaHei";
 color: #909399;
 }
 .clearfix:before,
 .clearfix:after {
 display: table;
 content: "";
 }
 .clearfix:after {
 clear: both
 }
 .el-card {
 min-width: 100%;
 height: 100%;
 margin-right: 20px;
 /*transition: all .5s;*/
 }
 .el-card:hover{
 margin-top: -5px;
 }
 .el-row {
 margin-bottom: 20px;
 display: flex;
 flex-wrap: wrap
 }
 .el-col {
 border-radius: 4px;
 align-items: stretch;
 margin-bottom: 40px;
 }
</style>

补充知识：vue element框架中el-row控件里按列排列失效问题的解决

最近我在使用vue的ui框架element-ui，可能是自己经验不足，遇到了很奇怪的问题，在这里特意把解决的步骤记录一下，希望能对大家有所帮助。

首先我使用的分栏间隔的布局方式，参照官网上的例子：


<el-row :gutter="20">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>


<style>
 .el-row {
 margin-bottom: 20px;
 &:last-child {
  margin-bottom: 0;
 }
 }
 .el-col {
 border-radius: 4px;
 }
 .bg-purple-dark {
 background: #99a9bf;
 }
 .bg-purple {
 background: #d3dce6;
 }
 .bg-purple-light {
 background: #e5e9f2;
 }
 .grid-content {
 border-radius: 4px;
 min-height: 36px;
 }
 .row-bg {
 padding: 10px 0;
 background-color: #f9fafc;
 }
</style>

应该效果如下图：

但是我在参考例子后，代码如下：

App.vue


<template>
 <div id="app">
<el-row :gutter="20">
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
 <el-col :span="6"><div class="grid-content bg-purple">1</div></el-col>
</el-row>
</div>
</template>


<style>
 .el-row {
 margin-bottom: 20px;
 }
 .el-col {
 border-radius: 14px;
 }
 .bg-purple {
 background: #d3dce6;
 }
 .grid-content {
 border-radius: 14px;
 min-height: 36px;
 }
</style>

main.js


// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'//A Vue.js 2.0 UI Toolkit for Web
Vue.use(ElementUI);
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
 el: '#app',
 router,
 components: { App },
 template: '<App/>'
})

可是效果如下：

奇怪了，为何布局变成了纵向，明明row中的布局应该是按列排列的。经过排查发现自己少了这一行：import ‘element-theme-chalk';

也就是代码应该如下：

main.js


// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'//A Vue.js 2.0 UI Toolkit for Web
import 'element-theme-chalk';
Vue.use(ElementUI);
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
 el: '#app',
 router,
 components: { App },
 template: '<App/>'
})
