grid 布局就是给父元素（容器）添加display:grid,然后使子元素（项目）改变布局，
1 2 3 4 5 6 7 8 9
上面九个正方形的代码如下：没有给正方形设定宽度，是为了方便观察css效果
.seven{
background:#f1c40f;
line-height:100px;
color:#fff;
font-size: 40px;
text-align: center;
}
1.grid-template-columns 属性 | grid-template-rows 属性
grid-template-columns 定义每一列的列宽
grid-template-rows 定义每一行的行高
单位有：fr(分数)、%、px
.section-one-1{
width:400px;
display: grid;
grid-template-columns: 1fr 1fr 1fr;
grid-template-rows: 1fr 1fr 1fr;
}
把九个宫格分成了三行三列，每一个项目的空间占1/3*1/3=1/9
123456789
如果容器的宽度没有限定，就会以容器最大的宽度来等比例排列
.section-one-2{
display: grid;
grid-template-columns: 1fr 1fr 1fr;
grid-template-rows: 1fr 1fr 1fr;
}
123456789
2.如果要使容器内项目居中，则可使用justify-items属性|align-items 属性|place-items 属性
justify-items属性设置单元格内容的水平位置（左中右 默认）start | center | end | stretch;
align-items属性设置单元格内容的垂直位置（上中下 默认）start | center | end | stretch;
place-items属性是align-items属性和justify-items 属性的合并简写形式。
place-items: align-items(start) justify-items(end)
当容器宽度大于项目的集合宽度，当容器高度大于项目的集合高度，项目会自动居中在每两列之间，如下代码
.section-two-1 {
display: grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
place-items: center center;
height:500px;
}
123456789
3.grid-row-gap 属性|grid-column-gap 属性|grid-gap 属性
grid-row-gap 属性设置行与行的间隔（行间距）
grid-column-gap 属性设置列与列的间隔（列间距）
grid-gap属性是grid-row-gap和grid-column-gap的合并简写形式
grid-gap: grid-row-gap grid-column-gap
.section-three-1{
display: grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
grid-row-gap: 20px;
grid-column-gap: 30px;
}
123456789
4.grid-template-areas属性 |grid-area属性
网格布局允许指定"区域"（area），一个区域由单个或多个单元格组成。grid-template-areas属性用于定义区域
这个属性需要搭配项目（儿子）的grid-area属性使用
grid-area属性指定项目放在哪一个区域。
.section-four-1{
display: grid;
grid-template-columns: 150px 150px 150px;
grid-template-rows:150px 150px 150px;
grid-template-areas:"header header header""header header header"
"two three four";
}
.section-four-1>span:first-child{
grid-area: header;}
.section-four-1>span:nth-child(2){
grid-area: two;}
.section-four-1>span:nth-child(3){
grid-area: three;}
.section-four-1>span:last-child{
grid-area: four;}
2345.repeat() 函数
repeat 函数作用在可以把重复的简写，代码如下。第一个参数为重复的次数，第二个参数是重复的数值
.section-five-1{
width:500px;
display: grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
}
123456789
repeat()重复某种模式也是可以的。
如下图定义了6列，第一列和第四列的宽度为100px，第二列和第五列为220px，第三列和第六列为1fr。
.section-five-2{
display: grid;
grid-template-columns:repeat(2,100px 220px 1fr);
grid-template-rows: repeat(3,1fr);
}
123456789
6.minmax(min,max) 函数
minmax(min,max) 函数产生一个长度范围，表示长度就在这个范围之中。它接受两个参数，分别为最小值和最大值。
.section-six-1{
display: grid;
grid-template-columns:1fr 1fr minmax(50px, 100px);
grid-template-rows: 1fr 1fr minmax(50px, 150px);
}
123456789
7.grid-auto-flow 属性
grid-auto-flow属性决定，默认值是row，即"先行后列"。也可以将它设成column，变成"先列后行"。
.section-seven-1{
display: grid;
grid-template-columns:repeat(3,1fr);
grid-template-rows:repeat(3,1fr);
grid-auto-flow: column;
}
123456789
8.justify-content属性|align-content属性|place-content属性
justify-content属性是整个内容区域在容器里面的水平位置（左中右）start | end | center | stretch | space-around | space-between | space-evenly;
align-content属性是整个内容区域的垂直位置（上中下）start | end | center | stretch | space-around | space-between | space-evenly;
place-content属性：align-content justify-content
justify-content属性值只能体现在grid-template-columns中某一个值为auto才会有效果。如下
.section-eight-1{
display: grid;
grid-template-columns:150px auto 150px;
grid-template-rows:repeat(3,1fr);
place-items: center center;
height: 500px;
justify-content: start;
}
123456789
justify-content:stretch;恢复默认情况。如下
.section-eight-2{
display: grid;
grid-template-columns:150px auto 150px;
grid-template-rows:repeat(3,1fr);
place-items: center center;
height: 500px;
justify-content:stretch;
}
123456789
justify-content:space-around;每个项目两侧的间隔相等。所以，项目之间的间隔比项目与容器边框的间隔大一倍。如下
.section-eight-3{
display: grid;
grid-template-columns:150px auto 150px;
grid-template-rows:repeat(3,1fr);
place-items: center center;
height: 500px;
justify-content:space-around;
}
123456789
justify-content:space-between;项目与项目的间隔相等，项目与容器边框之间没有间隔。如下
.section-eight-4{
display: grid;
grid-template-columns:150px auto 150px;
grid-template-rows:repeat(3,1fr);
place-items: center center;
height: 500px;
justify-content:space-between;
}
123456789
justify-content:space-evenly;项目与项目的间隔相等，项目与容器边框之间也是同样长度的间隔。如下
.section-eight-5{
display: grid;
grid-template-columns:150px auto 150px;
grid-template-rows:repeat(3,1fr);
place-items: center center;
height: 500px;
justify-content:space-evenly;
}
123456789
align-content属性和justify-content属性是一样的
9. grid-column-start 属性 | grid-column-end 属性
grid-row-start 属性 | grid-row-end 属性
这些属性定义在项目上面.
grid-column-start属性：左边框所在的垂直网格线
grid-column-end属性：右边框所在的垂直网格线
grid-row-start属性：上边框所在的水平网格线
grid-row-end属性：下边框所在的水平网格线
.section-nine-1{
width:400px;
display:grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
}
.section-nine-1>span:first-child{
grid-column-start: 2;
grid-column-end: 4;
}
1号项目的左边框是第二根垂直网格线，右边框是第四根垂直网格线。如下
123456789
上图中，只指定了1号项目的左右边框，没有指定上下边框，所以会采用默认位置，即上边框是第一根水平网格线，下边框是第二根水平网格线。
下面的例子是指定四个边框位置的效果。
1号项目的左边框是第1根垂直网格线，右边框是第3根垂直网格线。上边框是第2根水平网格线，下边框是第4根水平垂直线。如下
.section-nine-2{
width:400px;
display:grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
}
.section-nine-2>span:first-child{
grid-column-start: 1;
grid-column-end: 3;
grid-row-start: 2;
grid-row-end: 4;
}
123456789
这四个属性的值还可以使用span关键字，表示"跨越"，即左右边框（上下边框）之间跨越多少个网格。
上面代码表示，1号项目的左边框距离右边框跨越3个网格。上边框距离下边框跨越2个网格
.section-nine-3{
width:400px;
display:grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
}
.section-nine-3>span:first-child{
grid-column-start:span 3;
grid-row-start:span 2;
}
123456789
grid-column 属性 | grid-row 属性
grid-column属性是grid-column-start和grid-column-end的合并简写形式
grid-row属性是grid-row-start属性和grid-row-end的合并简写形式。
.section-nine-3>span:first-child{
grid-column-start:1/3;
grid-row:2/4;
}
.section-nine-3>span:first-child{
grid-column-start: 1;
grid-column-end: 3;
grid-row-start: 2;
grid-row-end: 4;
}
10.justify-self 属性 | align-self 属性 | place-self 属性
justify-self属性设置单元格内容的水平位置（左中右），跟justify-items属性的用法完全一致，但只作用于单个项目。
justify-self属性设置单元格内容的垂直位置（上中下），跟align-items属性的用法完全一致，也是只作用于单个项目。
place-self属性是align-self属性和justify-self属性的合并简写形式。
如果省略第二个值，place-self属性会认为这两个值相等。
place-self: (align-self) (justify-self);
两个属性都可以取四个值。start：对齐单元格的起始边缘。 end：对齐单元格的结束边缘。
center：单元格内部居中。stretch：拉伸，占满单元格的整个宽度（默认值）。
.section-ten-1{
width:400px;
display:grid;
grid-template-columns: repeat(3,1fr);
grid-template-rows: repeat(3,1fr);
}
.section-ten-1>span:first-child{
justify-self: start;
}
