那么本章节,我们使用Vue3、Element-plus构建组图文章;
通过基础的 24 分栏,迅速简便地创建布局。
使用单一分栏创建基础的栅格布局。
通过 row 和 col 组件,并通过 col 组件的 span 属性我们就可以自由地组合布局。
<template>
<el-row>
<el-col :span="24"><div class="grid-content bg-purple-dark">div>el-col>
el-row>
<el-row>
<el-col :span="12"><div class="grid-content bg-purple">div>el-col>
<el-col :span="12"><div class="grid-content bg-purple-light">div>el-col>
el-row>
<el-row>
<el-col :span="8"><div class="grid-content bg-purple">div>el-col>
<el-col :span="8"><div class="grid-content bg-purple-light">div>el-col>
<el-col :span="8"><div class="grid-content bg-purple">div>el-col>
el-row>
<el-row>
<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-col :span="6"><div class="grid-content bg-purple-light">div>el-col>
el-row>
<el-row>
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple-light">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple-light">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple-light">div>el-col>
el-row>
template>
分栏之间存在间隔。
Row 组件 提供 gutter 属性来指定每一栏之间的间隔,默认间隔为 0。
<template>
<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>
template>
通过基础的 1/24 分栏任意扩展组合形成较为复杂的混合布局。
<template>
<el-row :gutter="20">
<el-col :span="16"><div class="grid-content bg-purple">div>el-col>
<el-col :span="8"><div class="grid-content bg-purple">div>el-col>
el-row>
<el-row :gutter="20">
<el-col :span="8"><div class="grid-content bg-purple">div>el-col>
<el-col :span="8"><div class="grid-content bg-purple">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
el-row>
<el-row :gutter="20">
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
<el-col :span="16"><div class="grid-content bg-purple">div>el-col>
<el-col :span="4"><div class="grid-content bg-purple">div>el-col>
el-row>

mock数据是JSON格式的数据,会使用axios去加载,解析后放置到Layout 布局里去显示
