网格布局简介

CSS3网格布局是让开发人员设计一个网格并将内容放在这些网格内。而不是使用浮动制作一个网格，实际上是你将一个元素声明为一个网格容器，并把元素内容置于网格中。

有一些浏览器是不支持网格布局的，可以从caniuse这个网站查看各个浏览器是否支持这些css3中的新属性,绿色表示支持，红色表示不支持，另一种颜色表示部分支持，如图（查看各个浏览器是否支持grid布局）：

通过下面这张图片可以了解网格布局的基本概念

先来个表情包happy一下吧哈哈哈

代码部分

页面布局：

公共样式css:

* {
    margin: 0;
    padding: 0;
  }

html, body {
  height: 100%;
  width: 100%;
  overflow-x: hidden;
}

body {
  line-height: 1.6;
  background-color: #EFEFF4;
}
.container{
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  font-size: 0.37037037rem;
}
.page__hd {
  padding: 10px;
}
.page__title {
  text-align: left;
  color: #716F76;
}
.grids {
  display: grid;
  grid-template-columns: repeat(3,3.33333333rem);
  grid-template-rows: repeat(3,3.33333333rem);
}
.grid {
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: column;
  text-decoration: none;
  background-color: #FFFFFF;
  color: #707070;
}

在grids中设置网格布局，display:grid;grid-template-columns属性设置网格布局中每列的宽度，grid-template-rows属性设置网格布局中每行的高度，由于在head中导入了淘宝的flexible，所以设置宽高时用了相对单位rem，grid-template-columns: repeat(3,3.33333333rem)相当于grid-template-columns: 3.33333333rem 3.33333333rem 3.33333333rem,grid-template-rows: repeat(3,3.33333333rem)同理；

在微信的界面中是有“边框的”，这里用了伪元素来实现
代码如下：

.grids {
    position: relative;
    overflow: hidden;
}
.grids:before {
   content: "";
   position: absolute;
   top: 0;
   left: 0;
   right: 0;
   height: 1px;
   border-top: 1px solid #E5E5E5;
   /* 1px 问题 retina 手机 1px很粗*/
   /* -webkit-transform: scaleY(0.5);
   transform: scaleY(0.5);
   -webkit-transform-origin: 0 0;
   transform-origin: 0 0; */
}
.grids:after {
    content: "";
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
    height: 1px;
    border-bottom: 1px solid #E5E5E5;
 }
 .grid {
     position: relative;
     float: left;
     padding: 20px 10px;
     box-sizing: border-box;
 }
 .grid:before {
     content: "";
     position: absolute;
     right: 0;
     top: 0;
     bottom: 0;
     width: 1px;
     border-right: 1px solid #E5E5E5;
 }
 .grid:after {
    content: "";
    position: absolute;
    right: 0;
    left: 0;
    bottom: 0;
    height: 1px;
    border-bottom: 1px solid #E5E5E5;
}

有的手机存在“1px问题”，可以通过transform和transform-origin属性来解决这个问题
