.grid-container {
  display: grid;
  grid-template-columns: auto auto auto auto auto auto;
  grid-gap: 10px;
  background-color: #2196F3;
  padding: 10px;
}

.grid-container > div {
  background-color: rgba(255, 255, 255, 0.8);
  text-align: center;
  padding: 20px 0;
  font-size: 30px;
}

.item8 {
  grid-area: 2 / 1 / span 2 / span 3;
}
</style>
</head>
<body>

<p>您可以使用 <em>grid-area</em> 属性来规定在何处放置项目。</p>

<p>语法是：grid-row-start / grid-column-start / grid-row-end / grid-column-end.</p>

<p>Item8 将在 row-line 2 和 column-line 1，并横跨两行三列：</p>
