没有滚动条就无法工作

Question

所以我试图让一个模式在主页没有滚动条的情况下工作。模态内部是不同高度的照片。当适合视图高度的照片位于模式内部时，没有滚动条。当它是一个更高的图像时，滚动条就会出现。

我正在努力做到无论照片大小都不会显示滚动条。为了简洁起见，我删除了一些重复的代码。我添加了图片以进行说明。

我试过为不同的属性设置视图高度，但似乎没有任何效果。

感谢@Danield 和他在下面的回答，我得以解决这个问题：

.

TL;DR 并编辑为 Bootstrap 5，

.img-fluid {
    max-height: calc(100vh - 225px);
}
