Question

我正在尝试使垂直屏幕图像适合模式内部的屏幕像

但是，相反，如果图像大于屏幕尺寸，则它会开始滚动并具有滚动功能，而水平图像都可以。

我尝试过玩.imageHeight类。

我已添加图片：

当我添加max-height: 300px;时，它会挤压图像，
max-height 100%根本什么都没做，
添加image-fluid类似乎根本不起作用，
尝试了object-fit: scale-down;，但似乎使图片变小了但屏幕仍不适合。

我在这里创建了Codepen：https://codepen.io/anon/pen/mYdyrO

.imageHeight {
  max-height: 100%;
}

Answer 1

只需对转盘滑块和滑块图像使用max-height。
使用object-fit:cover的图像将填充其框的高度和宽度，再次保持其宽高比，但在此过程中通常会裁剪图像。

可选地，我已使用@media进行响应，以后您可以根据需要调整max-height。

.imageHeight {
    max-height: 460px;
    object-fit: cover;
    -o-object-fit: cover;
}

.carousel.slide {
    max-height: 460px;
}

@media (max-width:767px) {
    .imageHeight {
        max-height: 260px;
        object-fit: cover;
        -o-object-fit: cover;
    }
    .carousel.slide {
        max-height: 260px;
    }
}

使用position:absolute方法：

.carousel-item {
  padding-bottom: 56%;
  overflow: hidden;
  position: relative;
}
.imageHeight {
    object-fit: cover;
    -o-object-fit: cover;
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
}
