CSS网格项目会溢出子网格容器和父网格容器（高度）

问题描述 投票：0回答：1

我正在使用父CSS网格容器body [2x2]，在其内部(row 1 / col 2)中使用子网格容器main [1x4]。问题是ul容器的最后一个网格项目main溢出了容器。如果滚动到页面底部，您会看到。

通常我期望main和body网格容器都可以扩展到网格项目所需的高度？！但它看起来根本没有响应能力。

提示：如果通过浏览器工具放大和缩小页面，则此问题将变得更加明显或得到解决。

在.main类中更改此行：

grid-template-rows: 51px fit-content(30%) auto auto;

我希望这可以帮助您。
