为什么我的图像在显示弹性的媒体查询中拉伸

Question

我有一个带有一类author-pic的图像，它的工作方式我想要它，除了在第二个到最后一个媒体查询它水平拉伸时，设置了display flex。我知道你不应该对显示flex的孩子使用％，但是author-pic不是直接的孩子，这是否意味着你在使用display flex时不能对任何孩子使用％？如果是这样我怎么能解决这个问题，因为flex-basis似乎也没有用，我假设因为作者pic不是直接的孩子。

Answer 1

如果您希望图像正确缩放，则只需使用宽度或仅使用高度。您的图像看起来很奇怪，因为您将高度设置为25％。删除它，它应该工作。如果您需要使用两者，请确保您的比例正确，例如4：3

Answer 2

使用align-items。默认值为stretch，此处将应用此值。您似乎想要使用flex-start。
