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%;}

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-itemsjustify-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 div { 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 div { 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-rowsgrid-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>
