分享最近使用的一套elementUI的使用总结

总结于ElementUI官网

Basic

（一）Layout布局

el-row / el-col

其中最大为24个分区

  • span控制对应的占位宽度
  • gutter控制区域之间的间距（默认为0）
  • offset控制跳跃距离

<el-row :gutter="20">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
  <el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
  <el-col :span="12" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

代码运行结果为：

img1

  • flex布局 便于控制布局（通过justify控制对应位置）

<el-row type="flex" class="row-bg">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="center">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="end">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="space-between">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="space-around">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

代码运行结果为：
