															+* Name lines (space between columns or rows) like this: `grid-template-columns: [first-line] 1fr [second-line] 1fr [last-line];` 
														 | 
													
												
											
												
													
														| 
														 | 
														
															 
														 |

														 | 
													
												
											
												
													
														| 
														 | 
														
															 
														 |
