Chrome未检测自举轮播的自动高度

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

.carousel .carousel-inner .carousel-item .carousel-img { 
    width: 100%; 
    height: 400px; 
    background-repeat: no-repeat; 
    background-position: center center; 
    background-attachment: fixed; 
    background-size: cover; 
    background-color: red; 
}

我有上面的代码来维护调整大小的引导轮播的高宽比，但它不适用于chrome。Chrome未检测自举轮播的自动高度

该网页是下一个：http://huertalia.mx/UniversidadesWP/site/index.html 如果你使用safari或firefox进行测试，并调整屏幕的大小将工作正常。如果您使用chrome，则传送带无法正常工作。

下面是旋转木马
