我开始使用旧的 stackoverflow 问题中的现有模板测试 Flexbox。所以，我试图改变图像大小以适应父 div。
我在 HTML 中添加了这一行:
max-width: 50px; height: auto; margin:auto; vertical-align:middle; width: 100%; margin-left: .5rem;
对于每个 img 但是如果我改变屏幕尺寸，它看起来并不总是很好。我尝试使用填充，但在某些情况下图像会被剪切。

您的问题源于在图像元素上使用 margin-left 和宽度。当你这样做时，图像获得了元素的整个宽度，但被边缘推到了一边，你得到了你看到的剪裁。
对此有一些修复。您可以将边距样式移动到父元素(如我下面的示例片段所示)。或者，只要您使用的是现代浏览器，您就可以使用 calc 设置宽度，它允许您混合宽度类型(width: calc(100% - .5rem); ).
注意:.row 类将 margin-right 和 margin-left 设置为 -.5rem这就是导致整行在左侧和右侧裁剪的原因(我假设您的区域在您的实现中没有达到全页宽度，因此您不应该遇到这个问题)。不过，我已经在下面评论了这两行。
