html - 响应式 flexbox 问题中的图像

Question

当屏幕尺寸发生变化时，我试图让植物图像适应具有响应高度和宽度的 flexbox ，但它似乎不起作用。它还改变了 flex box 的形状以适应图像大小，这不是我想要的。图像应该完全适合 flex box 而不改变它的形状并且仍然是响应式的。我究竟做错了什么？任何帮助，谢谢。

Answer 1

您可以将容器设置为相对位置，将元素设置为绝对位置。因为它是伪元素，所以在您的示例中保存每个框中的尺寸。

.flex-post {
  ...
  position: relative;
  overflow: hidden;
}

img {
  position: absolute;
  max-width: 100%;
}

此外，如果您需要图像始终覆盖每个框，无论图像大小如何，您可以使用object-fit。属性(property)。或者，使用背景而不是内联图像以获得更好的浏览器支持 background-size: cover;。

img {
  position: absolute;
  width: 100%;
  height: 100%;
  object-fit: cover;
}
