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;

justify-content/align-content

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;

  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>

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 {
