Vant Layout 布局
介绍
Layout 提供了van-row和van-col两个组件来进行行列布局
引入
import Vue from 'vue';
import { Col, Row } from 'vant';
Vue.use(Col);
Vue.use(Row);
代码演示
基本用法
Layout 组件提供了24列栅格，通过在Col上添加span属性设置列所占的宽度百分比此外，添加offset属性可以设置列的偏移宽度，计算方式与 span 相同
<van-row>
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
</van-row>
<van-row>
<van-col span="4">span: 4</van-col>
<van-col span="10" offset="4">offset: 4, span: 10</van-col>
</van-row>
<van-row>
<van-col offset="12" span="12">offset: 12, span: 12</van-col>
</van-row>
设置列元素间距
通过gutter属性可以设置列元素之间的间距，默认间距为 0
<van-row gutter="20">
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
</van-row>
Flex 布局
将 type 属性设置为 flex 可以启用 flex 布局，便于进行灵活的对齐
<!-- 左对齐 -->
<van-row type="flex">
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
</van-row>
<!-- 居中 -->
<van-row type="flex" justify="center">
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
</van-row>
<!-- 右对齐 -->
<van-row type="flex" justify="end">
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
</van-row>
<!-- 两端对齐 -->
<van-row type="flex" justify="space-between">
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
</van-row>
<!-- 每个元素的两侧间隔相等 -->
<van-row type="flex" justify="space-around">
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
<van-col span="6">span: 6</van-col>
</van-row>
