								`auto-fit` 效果几乎和 `auto-fill` 一样。 不同点仅在于,当容器的大小大于各网格项之和时,`auto-fill` 会持续地在一端放入空行或空列,这样就会使所有网格项挤到另一边;而 `auto-fit` 则不会在一端放入空行或空列,而是会将所有网格项拉伸至合适的大小。

							 | 
							
								
							 | 
							
							
								**注意:**如果容器宽度不足以将所有网格项放在同一行,余下的网格项将会移至新的一行。

								在第二个网格中,请用 `auto-fit` 和 `repeat` 来填充网格,其中列宽的最小值为 `60px`,最大值为`1fr`。 你可以调整最右侧的预览区来查看效果。

								`container2` class 应该有一个 `grid-template-columns` 属性,通过 `repeat` 和 `auto-fit` 将网格中的列的宽度设置为最小 `60px`,最大 `1fr`。
