grid布局

加在父元素上的属性

grid-template-columns/grid-template-rows

• 定义元素的行或列的宽高

• 如果父元素被等分成了9等分，则，不管有多少个子元素，都显示9等分

• grid-template-columns: 33% 33% 33%;可以写成grid-template-columns:repeat(3, 33%);

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; } .container1 {   grid-template-columns: 33% 33% 33%;   grid-template-rows: 33% 33% 33%; }

<div class="container container1">   <div class="item item-1"></div>   <div class="item item-2"></div> </div>

grid-template-areas

• 父元素的grid-template-areas配合子元素的grid-area定义网格区域

• 一个句点表示一个空的网格单元

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; } .container2 {   grid-template-columns: 1fr 1fr 1fr 1fr;   grid-template-rows: 1fr 1fr 1fr;   grid-template-areas: "header header . footer"     "main main . sidebar"     "main main . sidebar"; }  .container2 .item-1 {   grid-area: header; }  .container2 .item-2 {   grid-area: main; }  .container2 .item-3 {   grid-area: sidebar; }  .container2 .item-4 {   grid-area: footer; }

<div class="container container2">   <div class="item item-1">header</div>   <div class="item item-2">main</div>   <div class="item item-3">sidebar</div>   <div class="item item-4">footer</div> </div>

grid-column-gap/grid-row-gap/grip-gap

• 指网格线的大小，也可以说是网格子项之间的间距

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; } .container3 {   grid-template-columns: repeat(3, 30%);   grid-template-rows: repeat(3, 30%);   grid-column-gap: 2%;   grid-row-gap: 2%; }

<div class="container container3">   <div class="item item-1"></div>   <div class="item item-2"></div>   <div class="item item-3"></div>   <div class="item item-4"></div>   <div class="item item-5"></div>   <div class="item item-6"></div>   <div class="item item-7"></div>   <div class="item item-8"></div>   <div class="item item-9"></div> </div>

justify-items/align-items

• justify-items让子元素的内容和纵向列轴对齐

• align-items让子元素的内容和横向行轴对齐

• 两个属性都有四个值

• 我的例子中，为了方便对比，嵌套了grid网格

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; }  .container4 {   width: 400px;   height: 200px;   grid-template-columns: repeat(4, 25%);   grid-template-rows: repeat(2, 50%); } .container4 .item {   display: grid; } .container4 .item p {   background-color: coral;   border: 1px dashed #aaa } .container4 .item-1 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   justify-items: start; } .container4 .item-2 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   justify-items: end; } .container4 .item-3 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   justify-items: center; } .container4 .item-4 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   justify-items: stretch; } .container4 .item-5 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   align-items: start; } .container4 .item-6 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   align-items: end; } .container4 .item-7 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   align-items: center; } .container4 .item-8 {   grid-template-columns: repeat(2, 50%);   grid-template-rows: repeat(2, 50%);   align-items: stretch; }

<div class="container container4">   <div class="item item-1">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-2">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-3">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-4">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-5">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-6">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-7">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-8">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>

justify-content/align-content

• 设置子元素的对齐方式，justify表示纵向，align表示横向

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; }  .container5 {   width: 700px;   height: 200px;   grid-template-columns: repeat(7, 14%);   grid-template-rows: repeat(2, 50%); }  .container5 .item {   display: grid; }  .container5 .item p {   background-color: coral;   border: 1px dashed #aaa }  .container5 .item-1 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: start; }  .container5 .item-2 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: end; }  .container5 .item-3 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: center; }  .container5 .item-4 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: stretch; }  .container5 .item-5 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: space-around; }  .container5 .item-6 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: space-between; }  .container5 .item-7 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   justify-content: space-evenly; }  .container5 .item-8 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: start; }  .container5 .item-9 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: end; }  .container5 .item-10 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: center; }  .container5 .item-11 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: stretch; }  .container5 .item-12 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: space-around; }  .container5 .item-13 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: space-between; }  .container5 .item-14 {   grid-template-columns: repeat(2, 40%);   grid-template-rows: repeat(2, 40%);   align-content: space-evenly; }

<div class="container container5">   <div class="item item-1">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-2">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-3">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-4">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-5">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-6">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-7">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-8">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-9">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-10">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-11">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-12">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-13">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div>   <div class="item item-14">     <div>list</div>     <div>list</div>     <div>list</div>     <div>list</div>   </div> </div>

grid-auto-columns/grid-auto-rows

• grid-column后面的值如果是1 / 2形式，表示的是从第1列网格线开始到第2列网格线结束，如果这个属性定义的网格超出了父元素的范围，则会自动生成隐式网格

• grid-auto-columns和grid-auto-rows两个属性来指定这些隐式网格轨迹的宽度

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; }  .container6 {   width: 120px;   height: 180px;   grid-template-columns: 60px 60px;   grid-template-rows: 90px 90px;   grid-auto-columns: 60px; } .container6 .item-1 {   grid-column: 1 / 2;   grid-row: 2 / 3;   border: 1px solid #ccc; } .container6 .item-2 {   grid-column: 5 / 6;   grid-row: 2 / 3;   border: 1px solid #ccc; }

<div class="container container6">   <div class="item-1">1/2&2/3</div>   <div class="item-2">5/6&2/3</div> </div>

grid-auto-flow

• 没有网格元素的时候，自动排列

• row表示从左到右排列，column表示从上到下排列

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; }  .container7 {   display: grid;   width: 200px;   height: 40px;   grid-template-columns: 40px 40px 40px 40px 40px;   grid-template-rows: 40px 40px;   /* grid-auto-flow: row; */   grid-auto-flow: column; } .container7 .item-1 {   grid-column: 1;   grid-row: 1 / 3; }  .container7 .item-5 {   grid-column: 5;   grid-row: 1 / 3; }

<div class="container container7">   <div class="item item-1">1</div>   <div class="item item-2">2</div>   <div class="item item-3">3</div>   <div class="item item-4">4</div>   <div class="item item-5">5</div> </div>

加在子元素上的属性

grid-column-start/grid-column-end/grid-row-start/grid-row-end/grid-column/grid-row

• 定义网格开始或者结束的位置

• 值为数字，表示从这条线开始。值为span加数字，表示覆盖了这条线的位置

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; }  .container8 {   margin-top: 20px;   grid-template-columns: repeat(5, 20%);   grid-template-rows: repeat(5, 20%); } .container8 .item-1 {   grid-column-start: 2;   grid-column-end: 4;   grid-row-start: 1;   grid-row-end: 2; } .container8 .item-2 {   grid-column-start: 4;   grid-column-end: span 5;   grid-row-start: 2;   grid-row-end: span 5; } .container8 .item-3 {   grid-column: 1 / span 2;   grid-row: 2 / span 4; }

<div class="container container8">   <div class="item item-1">item-1</div>   <div class="item item-2">item-2</div>   <div class="item item-3">item-3</div> </div>

justify-self/align-self

• 网格子项内容与格线对齐

.container {   width: 200px;   height: 200px;   display: grid;   background-color: coral;   margin: 10px; }  .container .item {   border: 1px solid #ccc;   background-color: chocolate; } .container9 {   width: 400px;   height: 200px;   grid-template-columns: repeat(4, 25%);   grid-template-rows: repeat(2, 50%); } .container9 .item-1 {   justify-self: start; } .container9 .item-2 {   justify-self: end; } .container9 .item-3 {   justify-self: center; } .container9 .item-4 {   justify-self: stretch; } .container9 .item-5 {   align-self: start; } .container9 .item-6 {   align-self: end; } .container9 .item-7 {   align-self: center; } .container9 .item-8 {   align-self: stretch; }

<div class="container container9">   <div class="item item-1">item-1</div>   <div class="item item-2">item-2</div>   <div class="item item-3">item-3</div>   <div class="item item-4">item-4</div>   <div class="item item-5">item-5</div>   <div class="item item-6">item-6</div>   <div class="item item-7">item-7</div>   <div class="item item-8">item-8</div> </div>
