javascript - 如何从 Bootstrap 轮播中删除白色背景？

Question

我正在使用 Bootstrap v3.0。我将 carousal 幻灯片的过渡从水平更改为垂直。但是每当幻灯片发生变化时，都会在转换过程中出现白色背景。如何删除它？这是 fiddle :https://jsfiddle.net/amanturate/a9gcmg1r/

我希望轮播的高度为 520 像素，如果我使用 100% 则它不适合，我必须滚动才能看到整个轮播。

CSS 代码:

/* CUSTOMIZE THE CAROUSEL
-------------------------------------------------- */

/* Carousel base class */
.carousel {
 height: 520px;
 }

.carousel h1{
 color: white;
}

/* Since positioning the image, we need to help out the caption */
.carousel-caption {
 z-index: 10;
 background-image: linear-gradient(90deg,rgba(57,55,67,0.5),rgba(12,11,17,0.5));
 width: 100%;
 left: 0;
 padding-right: 90px;
}

/* Declare heights because of positioning of img element */
.carousel.vertical .item {
 height: 520px;
 background-color: #777;
 background-size: cover;
 background-position: center;
 background-repeat: no-repeat;
}
.carousel-inner > .item > img {
 position: absolute;
 top: 0;
 bottom: 0;
 left: 0;
 min-width: 100%;
 height: 520px;
}

.carousel-caption h1{font-size: 4em;}
.carousel-caption p{font-size: 2em;}

.carousel-control{
 z-index: 15;
}

.carousel-indicators{
 top: 40%;
 left: 100%;
 margin-left: -5%;
 z-index: 20;
 width: auto;
 padding-right: 10px;
}

.carousel-indicators li {
 display: block;
 margin-bottom: 5px;
}

.carousel-indicators .active {
 margin-bottom: 5px;
}


/* vertical carousel*/
.vertical .carousel-inner {
 height: 100%;
}

.carousel.vertical .item {
 -webkit-transition: 0.6s ease-in-out top;
 -moz-transition: 0.6s ease-in-out top;
 -ms-transition: 0.6s ease-in-out top;
 -o-transition: 0.6s ease-in-out top;
 transition: 0.6s ease-in-out top;
}

.carousel.vertical .active {
 top: 0;
}

.carousel.vertical .next {
 top: 100%;
}

.carousel.vertical .prev {
 top: -100%;
}

.carousel.vertical .next.left,
.carousel.vertical .prev.right {
 top: 0%;
}

.carousel.vertical .active.left {
 top: -100%;
}

.carousel.vertical .active.right {
 top: 100%;
}
/*vertical carousel setting ends*/
/* carousel customization ends */
