Question

我希望旋转木马中的图像能够响应特别是图像的高度。宽度是可以的，但它的高度只使图像的一半。有人能帮我吗？请给我一些想法。我只想要500px高度，我实现了这一点，但我希望我的图像高度达到100％。

这是图片

这是完整的图像

这是html代码。

Answer 1

尝试100vh，CSS3为我们提供视口相对单位。 100vw表示100％的视口宽度。 100vh; 100％的高度。在进行全屏幻灯片时非常方便。

试试这个：

.carousel-inner img{
   height: 100vh;
  width: 100%;
}

注意：对于Internet Explorer，它仅受ie11支持，对于其他浏览器没有问题。

更新：

将此类添加到您的样式中：

.item{
    height: 500px;
}

.item img {
    width: 100%;
    height: 100%;
}

这是一个演示：https://jsfiddle.net/qd4xhzvm/

Answer 2

试试这个

.item.active img {
  display: block;
  width: 100vw;
  height: 100vh;
  object-fit: contain;
}

Answer 3

我通过向max-height添加.carousel-inner img来解决这个问题。谢谢你们的努力。呵呵。

.carousel-inner img{
  width: 100%;
  max-height: 500px;
}
.carousel-inner{
  height: 500px;
}
