Question

我试图将此图标置于其div中，但似乎无法做到这一点。

我试过了top: 50%，但那不起作用。

该课程为ion-images，我知道我可以向其发送margin-top，但我想知道如何在中间正确设置它。

  margin: 0;

        color: #35E2FF;

Answer 2

如果您可以使用Flex，请尝试使用此功能。

.ion-images {
  height: 100%;
  flex-direction: column;
  display: flex;
  align-items: center;
  justify-content: center;
}

希望我可以帮到你。问候。
