Grid Areas - MDN Web Docs Glossary: Definitions of Web-related terms 编辑

A grid area is one or more grid cells that make up a rectangular area on the grid. Grid areas are created when you place an item using line-based placement or when defining areas using named grid areas.

Grid areas must be rectangular in nature; it is not possible to create, for example, a T- or L-shaped grid area.

In the example below I have a grid container with two grid items. I have named these with the grid-area property and then laid them out on the grid using grid-template-areas. This creates two grid areas, one covering four grid cells, the other two.

* {box-sizing: border-box;}

.wrapper {
    border: 2px solid #f76707;
    border-radius: 5px;
    background-color: #fff4e6;
}

.wrapper > div {
    border: 2px solid #ffa94d;
    border-radius: 5px;
    background-color: #ffd8a8;
    padding: 1em;
    color: #d9480f;
}

.wrapper {
  display: grid;
  grid-template-columns: repeat(3,1fr);
  grid-template-rows: 100px 100px;
  grid-template-areas:
    "a a b"
    "a a b";
}
.item1 {
  grid-area: a;
}
.item2 {
  grid-area: b;
}

<div class="wrapper">
   <div class="item1">Item</div>
   <div class="item2">Item</div>
</div>
