Bootstrap Carousel 中的图像如何具有相同的宽度？

Question

这实际上是从bootstrap网站上复制粘贴的，我也尝试过很多其他的东西，老实说我很难理解这些图片怎么会有相同的大小。如果您在旋转木马上单击下一步，您会看到高度总是不同的！

那我该怎么做呢？我试图更改内部轮播的属性，我创建的 div，不同的 div，但没有任何反应。尤其是当我使用自己的图像时，尺寸总是很奇怪。

Answer 1

每个图像中都有一个 class w-100，宽度为 bootstrap 默认值 class：100%。所以它会自动占据全宽。如果你想要相同的高度，有两种方法。 (1) 您必须更新相同宽度和高度的图像或制作 background-image 并给出 div width:100% 并指定其高度。

稍后谢谢我。
