>目标
- 使轮播成为视口大小的 60% x 60%。
- 使所有图像的大小与幻灯片显示的大小相同。
- 使旋转木马流动。
有谁知道如何实现这一点？这对我来说似乎是一个顽固的问题。

</html>谢谢！！
更改下面的颜色代码以满足您的需求
/*
Removes white gap between slides - change to base color of slide images
*/
.carousel {
background:#F5F5F5;
}
.carousel-item .img-fluid {
width:60%;
height: 60%;
}
/*
anchors are inline so you need it make them block to go full width
*/
.carousel-item a {
display: block;
width:60%;
height: 60%;
}
.carousel-control-prev {
color:#036;
margin-left: -.5rem;
z-index: 10;
}
.carousel-control-next {
color:#036;
margin-right: -.5rem;
z-index: 10;
}
.carousel-control-prev:hover {
color:#0084FF;
}
.carousel-control-next:hover {
color:#0084FF;
}如果你想为控件使用fontawesome图标，请使用这个
<a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
<i class="fas fa-chevron-circle-left fa-2x"></i>
以前
<a class="carousel-control-next text-faded" href="#carouselExampleControls" role="button" data-slide="next">
<i class="fas fa-chevron-circle-right fa-2x"></i>
下一个
除了下面的 css 规则外，我还将所有图像都设为 Bootstrap .img-fluid的成员。
html {
height: 100%;
width: 100%;
}
body {
height: 100%;
width: 100%;
display: block;
}
.carousel {
height: 60%;
width: 60%;
}
.carousel-item {
display: block;
width: 100%;
height: 100%;
