微信小程序网格布局

Question

我一直在尝试使用名为Vant Weapp（https://youzan.github.io/vant-weapp/#/col）的前端开发微信迷你程序，但是我却无法获得想要的gid布局，不确定是CSS还是我使用的布局方法错误

下面是程序的CSS

.mainPagePicBlock{
  border-radius: 8px;
  width: 160px;
}

.mainPagePics{
  border-top-left-radius: 8px;
  border-top-right-radius: 8px;
  width: 174px;
}

.mainContentText{
  font-size: 12px;
}

.maincard{
  /* border: red solid 1px; */
  box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2);
  transition: 0.3s;
  border-radius: 8px;
  margin-bottom: 10px;
  margin-right: 12px;
  margin-top: 10px;
  display: flex;

}

.container{
  padding: 2px;
}

.likeIcon{
  margin-left: 15px;
}

.numberOfLikes{
  margin-left: 8px;
  font-size: 12px 
}

这是HTML

<view>
<van-row>
<view class="container">
 <CustomNav title="Home" showProfile="{{true}}" profilePic="{{userInfo.avatarUrl}}" />
</view>
    <van-search class="search" span="24" value="{{ value }}" placeholder="search" />
    <van-tabs active="{{ active }}">
        <van-tab title="推荐"/>
        <van-tab title="附近"/>
        <van-tab title="视频"/>
        <van-tab title="旅行"/>
        <van-tab title="男士穿搭"/>
        <van-tab title="健身"/>
    </van-tabs>
