Flexbox图片高度调整大小

Question

我无法完全调整图像大小。

理想情况下，我希望调整图像的大小，以便该选项适合屏幕，当前仅适合宽度，为什么呢？是否可以通过仅使用CSS来获得我希望的行为，也许需要进行媒体查询？烧焦谷歌试图找到类似的问题，但没有运气！

谢谢！

更新：

为了澄清，我的问题是，如果窗口的高度足够小，图像将无法调整大小-标题消失，并且出现滚动条。我希望所有内容按比例缩小，因此不需要滚动条。

Answer 1

希望这就是您想要的。如果这是正确的答案！这就是我所做的。

• 将高度和宽度的容器类设置为100％，并将显示设置为flex和flex-direction: column，以便页眉，页脚和内容类垂直对齐。
• 现在，如果您将内容类flex的属性设置为1，它将占用其余的宽度和高度。
• 为选项类提供display: flex的属性并设置flex-direction: column，以使图像以及标题和描述垂直对齐。
• 通过将30px的min-height分配给标题和选项中的p，可以将其余空间分配给图片，我希望这是您想要的。

* {
  margin: 0;
  padding: 0;
}

.content {
  min-height: 100%;
  width: 100%;
  min-width: 100%;
  display: flex;
  flex-direction: row;
  box-sizing: border-box;
  padding: 30px 0;
}

.content .option {
  flex: 1;
  max-height: 100vh;
  min-width: 100%;
  display: flex;
  flex-direction: column;
}

.content .option img {
  height: calc(100% - 160px);
  width: 100%;
}
.content .option p {
  height: 20px;
}

.content .option p:nth-child(2) {
  height: 40px;
}

.header,
.footer {
