										 |  |  | 我们在上一次挑战中学到的 `grid-area` 属性还有另一种使用方式。 如果网格中没有定义区域模板,你也可以像这样为它添加一个模板: | 
					
						
							| 
									
										
										
										
											2020-02-11 21:39:15 +08:00
										 |  |  | 
 | 
					
						
							|  |  |  | ```css | 
					
						
							|  |  |  | item1 { grid-area: 1/1/2/4; } | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|

										 |  |  | 这里使用了你之前学习的网格线编号来定义网格项的区域。 上例中数字代表这些值: | 
					
						
							| 
									
										
										
										
											2020-02-11 21:39:15 +08:00
										 |  |  | 
 | 
					
						
							|  |  |  | ```css | 
					
						
							| 
									
										
										
										
											2021-02-06 04:42:36 +00:00
										 |  |  | grid-area: horizontal line to start at / vertical line to start at / horizontal line to end at / vertical line to end at; | 
					
						
							| 
									
										
										
										
											2020-02-11 21:39:15 +08:00
										 |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 因此,示例中的网格项将占用第 1 条水平网格线(起始)和第 2 条水平网格线(终止)之间的行,及第 1 条垂直网格线(起始)和第 4 条垂直网格线(终止)之间的列。 |

										 |  |  | 请用 `grid-area` 属性将 class 为 `item5` 的元素放置在第 3 条和第 4 条水平网格线,以及第 1 条和第 4 条垂直网格线之间的区域内。 |
