我一直在制作旋转木马，我从Bootstrap 4文档中复制了代码的大纲。但是当我编辑它看起来像我需要它时，指标不再在点击时改变幻灯片了吗？
我需要编辑什么来修复此问题？我认为它不是添加的CSS，因为我删除了它，它仍然无法正常工作。可能是HTML中的错误。但是，我无法看到我做错了什么。有人可以看看吗？
这是我的代码：
#hero-slider {
margin-bottom: 30px;
}
#hero-slider .carousel-indicators {
top: 30px;
justify-content: flex-start;
margin: 0;
padding-left: 15px;
padding-right: 15px;
}
.carousel-inner {
max-height: 500px;
}
.carousel-indicators li {
width: 20px;
height: 20px;
border-radius: 100%;
background-color: #f5821f;
}
.carousel-indicators li:not(:last-child) {
margin-right: 20px;
}
.carousel-indicators .active {
background-color: #fff;
}
.carousel-item:before {
-webkit-box-shadow: inset 0 20rem 40rem rgba(0, 0, 0, 0.5);
box-shadow: inset 0 20rem 40rem rgba(0, 0, 0, 0.5);
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
content: "";
}
.carousel-caption {
top: 50px;
bottom: auto;
}
.carousel-caption h5 {
color: #ffa70c;
font-size: 34px;
font-weight: 600;
line-height: 1.2;
margin-bottom: 25px;
}
.carousel-caption p {
color: #fff;
font-size: 18px;
letter-spacing: 1px;
font-weight: 600;
line-height: 1.2;
margin-bottom: 50px;

因为您的轮播ID是英雄 - 滑块，您需要将指标数据目标更改为此值而不是当前值：
从：
data-target="#carouselExampleIndicators"
为：
data-target="#hero-slider"
#hero-slider {
margin-bottom: 30px;
}
#hero-slider .carousel-indicators {
top: 30px;
justify-content: flex-start;
margin: 0;
padding-left: 15px;
padding-right: 15px;
}
.carousel-inner {
max-height: 500px;
}
.carousel-indicators li {
width: 20px;
height: 20px;
border-radius: 100%;
background-color: #f5821f;
}
.carousel-indicators li:not(:last-child) {
margin-right: 20px;
}
.carousel-indicators .active {
background-color: #fff;
}
.carousel-item:before {
-webkit-box-shadow: inset 0 20rem 40rem rgba(0, 0, 0, 0.5);
box-shadow: inset 0 20rem 40rem rgba(0, 0, 0, 0.5);
position: absolute;

}
.carousel-caption {

}
.carousel-caption h5 {
