这篇文章来介绍Ant中的Grid栅格,提一句,栅格是把横向区域等分为24份。划分之后的信息块称为盒子,每个盒子可以有多个区域组成(同一行的所有盒子的栅格加起来是24),建议横向排列的盒子数量最多四个,最少一个。

基础栅格

先来看一个基本的例子:

<a-row>
  <a-col :span="12">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">col-12</span>
    </div>
  </a-col>
  <a-col :span="12">
    <div class="grid-content bg-blue">
      <span style="color: white;">col-12</span>
    </div>
  </a-col>
</a-row>
<a-row>
  <a-col :span="8">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">col-8</span>
    </div>
  </a-col>
  <a-col :span="8">
    <div class="grid-content bg-blue">
      <span style="color: white;">col-8</span>
    </div>
  </a-col>
  <a-col :span="8">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">col-8</span>
    </div>
  </a-col>
</a-row>
<a-row>
  <a-col :span="6">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">col-6</span>
    </div>
  </a-col>
  <a-col :span="6">
    <div class="grid-content bg-blue">
      <span style="color: white;">col-6</span>
    </div>
  </a-col>
  <a-col :span="6">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">col-6</span>
    </div>
  </a-col>
  <a-col :span="6">
    <div class="grid-content bg-blue">
      <span style="color: white;">col-6</span>
    </div>
  </a-col>
</a-row>

<style scoped>
.bg-blue {
  background-color: #00a0e9;
}

.bg-blue-light {
  background-color: #43bdf5;
}

.grid-content {
  min-height: 36px;
  margin-top: 8px;
  margin-bottom: 8px;
  text-align: center;
  padding: 16px 0;

}
</style>

运行结果:

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-4Xm5qtD8-1638630491522)(C:\Users\lenovo\AppData\Roaming\Typora\typora-user-images\image-20211204182227973.png)]

每个<a-row>代表一行,每个<a-col>代表一列,<a-col>中的:span="6"表示该列占6个栅格。同一<a-row>标签中所有<a-col>的span数之和应该是24。

Flex 布局

栅格系统支持Flex布局,允许子元素在父节点内的水平对齐方式 - 居左、居中、居右、等宽排列、分散排列。子元素与子元素之间,支持顶部对齐、垂直居中对齐、底部对齐的方式。同时,支持使用 order 来定义元素的排列顺序。

Row上的属性

type & align & justify

type:布局模式,可选 flex

align:flex 布局下的垂直对齐方式:top middle bottom

justify:flex 布局下的水平排列方式:start end center space-around space-between

代码如下:

<p>Align Top</p>
    <a-row type="flex" justify="center" align="top" class="bg-gray">
      <a-col :span="4">
        <div class="grid-content bg-blue-light height-100">

      </a-col>
      <a-col :span="4">

      <a-col :span="4">

在这里插入图片描述

gutter

栅格间隔,可以写成像素值或支持响应式的对象写法来设置水平间隔 { xs: 8, sm: 16, md: 24}。或者使用数组形式同时设置 [水平间距, 垂直间距]1.5.0 后支持)。

代码如下:

<a-row :gutter="[16,32]">
        <a-col class="gutter-row" :span="6">
          <div class="gutter-box">
            col-6
          </div>
        </a-col>
        <a-col class="gutter-row" :span="6">
          <div class="gutter-box">
            col-6
          </div>
        </a-col>
        <a-col class="gutter-row" :span="6">
          <div class="gutter-box">

          </div>
        </a-col>
        <a-col class="gutter-row" :span="6">
          <div class="gutter-box">
            col-6
          </div>
        </a-col>
      </a-row>
      <a-row :gutter="[16,32]">
        <a-col class="gutter-row" :span="6">
          <div class="gutter-box">

        <a-col class="gutter-row" :span="6">
          <div class="gutter-box">

这里将水平间距设置成了16,垂直间距设置成了32。

Col上的属性

flex

flex 布局填充,是不用flex布局填充的时候,可以代替span

代码如下:

<a-divider orientation="left">
      Percentage columns
    </a-divider>
    <a-row type="flex">
      <a-col :flex="2">
        <div class="grid-content bg-blue-light">
          <span style="color: white;">
            2 / 5
          </span>
        </div>
      </a-col>
      <a-col :flex="3">
        <div class="grid-content bg-blue">
          <span style="color: white;">
            3 / 5
          </span>
        </div>
      </a-col>
    </a-row>
    <a-divider orientation="left">
      Fill rest
    </a-divider>
    <a-row type="flex">
      <a-col flex="100px">
        <div class="grid-content bg-blue-light">
          <span style="color: white;">
            100px
          </span>
        </div>
      </a-col>
      <a-col flex="auto">
        <div class="grid-content bg-blue">
          <span style="color: white;">
            auto
          </span>
        </div>
      </a-col>
    </a-row>
    <a-divider orientation="left">
      Raw flex style
    </a-divider>
    <a-row type="flex">
      <a-col flex="1 1 200px">
        <div class="grid-content bg-blue-light">
          <span style="color: white;">
            1 1 200px
          </span>

      <a-col flex="0 1 300px">

            0 1 300px

offset

栅格左侧的间隔格数,间隔内不可以有栅格,可以实现列的左右偏移,:offset="4" 将元素向右侧偏移了 4 个列(column)的宽度。

代码如下:

 <a-row>
      <a-col :span="8">
        <div class="grid-content bg-blue-light">
          <span style="color: white;">
            span="8"
          </span>
        </div>
      </a-col>
      <a-col :span="8" :offset="8">
        <div class="grid-content bg-blue">
          <span style="color: white;">
            span="8"  offset="8"
          </span>
        </div>
      </a-col>
    </a-row>
    <a-row>
      <a-col :span="6" :offset="6">
        <div class="grid-content bg-blue-light">
          <span style="color: white;">
            span="6"  offset="6"
          </span>
        </div>
      </a-col>
      <a-col :span="6" :offset="6">
        <div class="grid-content bg-blue">
          <span style="color: white;">
            span="6"  offset="6"
          </span>
        </div>
      </a-col>
    </a-row>
    <a-row>
      <a-col :span="12" :offset="6">
        <div class="grid-content bg-blue">
          <span style="color: white;">
            span="12"  offset="6"
          </span>
        </div>
      </a-col>
    </a-row>

运行结果:

pull & push

pull:栅格向左移动格数

push:栅格向右移动格数

代码如下:

    <a-row>
      <a-col :span="18" :push="6">
        col-18 col-push-6
      </a-col>
      <a-col :span="6" :pull="18">
        col-6 col-pull-18
      </a-col>
    </a-row>

span

栅格占位格数,为 0 时相当于 display: none,前面已经用过很多次了

响应式布局

  • xs <576px 时触发响应

  • sm ≥576px 时触发响应

  • md ≥768px 时触发响应

  • lg ≥992px 时触发响应

  • xl ≥1200px 时触发响应

  • xxl ≥1600px 时触发响应

代码如下:

<a-row>
  <a-col :xs="2" :sm="4" :md="6" :lg="8" :xl="10">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">
        小于276px:2 大于576px:4 大于768px:6 >=992px:8 大于1200px:10
      </span>
    </div>
  </a-col>
  <a-col :xs="20" :sm="16" :md="12" :lg="8" :xl="4">
    <div class="grid-content bg-blue">
      <span style="color: white;">
        小于276px:20 大于576px:16 大于768px:12 >=992px:8 大于1200px:4
      </span>
    </div>
  </a-col>
  <a-col :xs="2" :sm="4" :md="6" :lg="8" :xl="10">
    <div class="grid-content bg-blue-light">
      <span style="color: white;">

      </span>
    </div>
  </a-col>
</a-row>

运行结果:

注意:同一行内的,所有xs的值之和应该为24,所有sm的值之和应该为24,以此类推
