尝试让 Bootstrap 轮播按比例调整大小

Question

我试图让 Bootstrap 3 旋转木马随着屏幕尺寸缩小而按比例缩小 - 即我希望它在变小时保持相同的形状。开箱即用，它只是压扁（变得更窄，但不会更短）。我得到了图像来做我想做的事，但轮播的背景没有跟随。我已经尝试了各种各样的事情，但无法弄清楚。任何提示将不胜感激。谢谢！

很遗憾，我还不能post在这里拍照。基本上，当它缩小时，轮播的灰色背景会从图像下方突出。

Answer 1

尝试将 height:100% 添加到您的最后一个选择器。这将使您的容器保持其形状，同时在浏览器大小更改时仍会调整大小。

Answer 2

您是否按正确顺序加载 .js 文件？

我按这个顺序加载了它们....你的代码运行非常完美。

bootstrap.min.css
jquery-2.1.3.min.js
bootstrap.min.js
