grid

1.隐式的指定网格线反向指定了隐式的网格区域名称，命名的网格区域隐式的命名了网格线名称.

指定网格区域会给网格区域边线添加隐式的网格线名称。这些网格线的命名是基于网格区域来命名，只是在网格区域名称的后面添加后缀-start或-end.

<view class="grid">
  <view class='item1'>1</view>
  <view class='item'>2</view>
  <view class='item'>3</view>
  <view class='item'>4</view>
  <view class='item'>5</view>
  <view class='item'>6</view>
  <view class='item'>7</view>
  <view class='item'>8</view>
  <view class='item'>9</view>
</view>

page {
  color: #fff;
  font-size: 16px;
}

.grid {
  /* padding: 1%; */
  display: grid;
  grid-gap: 1px;
  line-height: 100px;
  grid-template-areas: "header header" "content sidebar" "footer footer";
  grid-template-rows: 80px 1fr 40px;
  grid-template-columns: 1fr 200px;
}

.item1 {
  /* grid-area: inner; */
  /* grid-row-start: header-start;
  grid-row-end: content-start;
  grid-column-start: footer-start;
  grid-column-end: sidebar-end; */
}

.item {
  text-align: center;
  background-color: #d94a6a;
}

.item1 {
  text-align: center;
  /* line-height: 300px; */
  background-color: #1aa034;
}

2.在这个示例中,header通过隐式的网格线名称设置其位置

page {
  color: #fff;
  font-size: 16px;
}

.grid {
  /* padding: 1%; */
  display: grid;
  grid-gap: 1px;
  line-height: 100px;
  grid-template-areas: "header header" "content sidebar" "footer footer";
  grid-template-rows: 80px 1fr 40px;
  grid-template-columns: 1fr 200px;
}

.item1 {
  /* grid-area: inner; */
  grid-row-start: header-start;
  grid-row-end: content-start;
  grid-column-start: footer-start;
  grid-column-end: sidebar-end;
}

.item {
  text-align: center;
  background-color: #d94a6a;
}

.item1 {
  text-align: center;
  /* line-height: 300px; */
  background-color: #1aa034;
}
