实现效果

步骤

1、下载bootstrap和jquery-3.6.0.min.js，并在html中引用，注意jq.js应在全部js前引用

2、按照官网https://v3.bootcss.com/javascript/的Carousel实例修改导入图片，body源码如下

<div class="box">
        <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
            <!-- Indicators -->
            <ol class="carousel-indicators">
                <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
                <li data-target="#carousel-example-generic" data-slide-to="1"></li>
                <li data-target="#carousel-example-generic" data-slide-to="2"></li>
                <li data-target="#carousel-example-generic" data-slide-to="3"></li>
            </ol>

            <!-- Wrapper for slides -->
            <div class="carousel-inner" role="listbox">
                <div class="item active">
                    <img src="./images/xuezhong_1.jpg" alt="...">
                    <div class="carousel-caption">
                        图片1
                    </div>
                </div>
                <div class="item">
                    <img src="./images/guimizhizhu_2.jpg" alt="...">
                    <div class="carousel-caption">
                        图片2
                    </div>
                </div>
                <div class="item">
                    <img src="./images/jianlai_3.jpg" alt="...">
                    <div class="carousel-caption">
                        图片3
                    </div>
                </div>
                <div class="item">
                    <img src="./images/yichang_4.jpg" alt="...">
                    <div class="carousel-caption">
                        图片4
                    </div>
                </div>

            </div>

            <!-- Controls -->
            <a class="left carousel-control" href="#carousel-example-generic" rel="external nofollow"  rel="external nofollow"  role="button" data-slide="prev">
                <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
                <span class="sr-only">Previous</span>
            </a>
            <a class="right carousel-control" href="#carousel-example-generic" rel="external nofollow"  rel="external nofollow"  role="button" data-slide="next">
                <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
                <span class="sr-only">Next</span>
            </a>
        </div>
</div>

在style.css调整图片样式

.box {
    width: 600px;
    height: 300px;
    background-color: pink;
    margin: 100px auto;
}

.carousel,
.carousel img {
    width: 100%;
    height: 300px !important;
}

在js中添加轮播时间

<script>
        $('.carousel').carousel({
            interval: 2000
        })
</script>

可根据官网的指引修改需要的相关样式
