本文仅供参考：
首先你要掌握的基础知识:
row 行概念
<el-row></el-row>
col 列概念
<el-col></el-col>
col组件的:span属性的布局调整,一共分为24栏:
代码示例:
<el-row>
<el-col :span="24"><div class="grid-content"></div></el-col>
</el-row>
效果展示:
代码示例：
<el-row>
<el-col :span="12"><div class="grid-content"></div></el-col>
</el-row>
效果展示:
row组件的:gutter属性来调整布局之间的宽度---分栏间隔
代码示例:
<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-row>
效果:
Col组件的:offset属性调整方块的偏移位置（每次1格/24格）
<el-row :gutter="20">
<el-col :span="6" :offset="6"><div class="grid-content"></div></el-col>
<el-col :span="6" :offset="6"><div class="grid-content"></div></el-col>
</el-row>
效果:
对齐方式:
row组件的type="flex"启动flex布局，再通过row组件的justify属性调整排版方式，属性值分别有:
justify=center 居中对齐
justify=start 左对齐
justify=end 右对齐
justify=space-between 空格间距在中间对齐
justify=space-around 左右各占半格空格对齐
<el-row type="flex" class="row-bg" justify="center">
<el-col :span="6"><div class="grid-content"></div></el-col>
</el-row>
效果:
响应式布局:
参考bootstrap的响应式，预设四个尺寸
xs <768px
sm ≥768px
md ≥992
lg ≥120
使用方式:
<el-row :gutter="10">
<el-col :xs="8" :sm="6" :md="4" :lg="3"><div class="grid-content bg-purple"></div></el-col>
<el-col :xs="4" :sm="6" :md="8" :lg="9"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :xs="4" :sm="6" :md="8" :lg="9"><div class="grid-content bg-purple"></div></el-col>
<el-col :xs="8" :sm="6" :md="4" :lg="3"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
练习示例:
<span class="field-label">方块选择:</span>
<!-- 选择屏幕框 -->
<select v-model="selected" @change="selectbj(selected)">
<option v-for="option in layouts" :value="option.value">
{{ option.name }}
</option>
</select>
data默认初始化数据:
selected: 0,
layouts: [
{ ‘name‘: ‘1x1模式‘, ‘value‘: ‘0‘ },
{ ‘name‘: ‘2x1模式‘, ‘value‘: ‘1‘ },
{ ‘name‘: ‘2x2模式‘, ‘value‘: ‘2‘ },
{ ‘name‘: ‘3x2模式‘, ‘value‘: ‘3‘ },
{ ‘name‘: ‘3x3模式‘, ‘value‘: ‘4‘ },
{ ‘name‘: ‘1+5模式‘, ‘value‘: ‘5‘ }
],
布局代码:
<el-main v-model="selected" >
<div class="block" style="height:400px">
<!-- {{selected}} -->
<div style="height:100%;width:100%" v-if="selected==0">
<!-- 1*1布局 -->
<el-row :gutter="10" type="flex" class="grid-one-contentheight" justify="center">
<el-col :span="24"></el-col>
</el-row>
</div>
<!-- 2*1布局 -->
<div style="height:100%;width:100%" v-else-if="selected==1">
<el-row :gutter="10" type="flex" class="row-bg el-row-two" justify="space-between">
<el-col :span="12"><div class="grid-content "></div></el-col>
<el-col :span="12"><div class="grid-content "></div></el-col>
</el-row>
</div>
<!-- 2*2 -->
<div style="height:100%;width:100%" v-else-if="selected==2">
<el-row :gutter="10" type="flex" class="row-bg" justify="center">

</div>
<!-- 3*2布局 -->

</el-row>
<br>
<el-row :gutter="10" type="flex" class="row-bg" justify="center">

<el-col :span="12"><div class="grid-content "></div></el-col>
<el-col :span="12"><div class="grid-content "></div></el-col>
</el-row>
</div>
<!-- 3*3模式 -->
<div style="height:100%;width:100%" v-else-if="selected==4">

<el-row :gutter="10" type="flex" class="row-bg" justify="center">
<el-col :span="8"><div class="grid-a-contentWidth"></div></el-col>
<el-col :span="8"><div class="grid-a-contentWidth"></div></el-col>
<el-col :span="8"><div class="grid-a-contentWidth"></div></el-col>
</el-row>

<el-col :span="8"><div class="grid-a-contentWidth"></div></el-col>
</el-row>
</div>
<!-- 模式 -->
