选择我的指示器以移动到幻灯片的下一部分

显示，单击后它不起作用。有没有什么原因导致这种方法不起作用？

<div id="slides" class="carousel slide" data-ride="carousel">
    <ul class="carousel-indicators">
        <li data-target="#slides" data-slide-to="0" class ="active"></li>
        <li data-target="#slides" data-slide-to="1"></li>
        <li data-target="#slides" data-slide-to="2"></li>
    </ul>

    <div class="carousel-inner active">
        <div class="carousel-item">
            <img src ="img/background.png">
        </div>

        <div class="carousel-item">
            <img src ="img/background2.png">
        </div>
    </div>

    <a class="carousel-control-prev" href="#slides" role="button" data-slide="prev">
        <span class="carousel-control-prev-icon" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
    </a> 

    <a class="carousel-control-next" href="#slides" role="button" data-slide="next"> 
        <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span>
    </a>

你需要做的只是在活动幻灯片的指示器上添加一些颜色，我已经使用了你的代码，并在css中添加了一行，你就可以看到结果了。

body {background: #333 !important;}
.carousel-indicators {
  bottom: -50px !important;
}
.carousel-indicators li.active {background: red;}
.carousel-item {color: white; font-size: 80px;}

<div id="slides" class="carousel slide" data-ride="carousel">

    <ul class="carousel-indicators">
        <li data-target="#slides" data-slide-to="0" class ="active"></li>
        <li data-target="#slides" data-slide-to="1"></li>
        <li data-target="#slides" data-slide-to="2"></li>
    </ul>

    <div class="carousel-inner active">
        <div class="carousel-item active">
           1
        </div>

        <div class="carousel-item">
            222
        </div>
<div class="carousel-item">
           3333
        </div>
    </div>

    <a class="carousel-control-prev" href="#slides" role="button" data-slide="prev">
        <span class="carousel-control-prev-icon" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
    </a> 

    <a class="carousel-control-next" href="#slides" role="button" data-slide="next"> 
        <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span>
    </a>
