为什么最大高度不能在Chrome浏览器中工作，而在IE 11中不能工作？

Question

我创建了下面的页面，我希望我的绿色div向下扩展而不影响下面的行。为此，我为 .grid_cell div设置了 max-height：164px; 样式，以便grid_cell类中包含的所有内容都将向下溢出，而不会更改grid_cell的高度。有什么办法可以使它像在Chrome中一样在IE 11中运行？如果您在IE 11中打开此页面，您会注意到，将鼠标悬停在div上方时，会将其下方的div向下推，但在Chrome中不会发生。为什么会这样？

Answer 1

即使在IE 11中，也可以正确应用max- CSS。

但是IE11认为兄弟元素具有相同的z-index，因此它们在视图中不可堆叠。

如果要在IE中正确显示该页面，请按如下所示编辑CSS：

.grid_cell {
  width: 144px;
  height: 165px;
}

.profile_container {
  position: absolute;
}
