我添加了bootstrap carousel，并更改为显示多个项目，尽管我遇到了一些问题
当我点击下一个标志一切正常，但当我点击上一个标志，出现多个标志都在一起之前修复本身，会发生什么？我该如何解决这个问题？
这里有一个链接到该项目，现场页面和完整的存储库
链接已删除，因为不再存在
代码如下：

<div id="carousel" class="carousel slide" data-ride="carousel">
      <ol class="carousel-indicators">
        <li data-target="#carousel" data-slide-to="0" class="active"></li>
        <li data-target="#carousel" data-slide-to="4"></li>
        <li data-target="#carousel" data-slide-to="8"></li>
        <li data-target="#carousel" data-slide-to="10"></li>
      </ol>

      <div class="carousel-inner">
        <div class="carousel-item active">
          <img class="d-block" src="https://wallpapercave.com/wp/ci1BoK6.jpg" alt="First slide">
          <div class="carousel-caption d-block">
            <h4>HTML</h4>
          </div>
        </div>

        <div class="carousel-item">

你的指标编号好像有点乱。此外，你有一个有点多的自定义CSS为我的口味。因此，我将其删除并使用原生Bootstrap类，例如mx-auto（margin horizontal auto）。
查看此代码片段，然后开始一点一点地添加您自己的自定义代码，直到您看到它中断的地方：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

<style>
    body {
        background: black;
    }
    .carousel-inner {
        height: 300px;
    }

    .carousel-item {
        height: 300px;
    }
    .carousel-item img {
        max-width: 250px;
        max-height: 250px;
    }
</style>


<div class="container">
    <div class="row">
        <div class="col mt-4">

                    <li data-target="#carousel" data-slide-to="3"></li>
                    <li data-target="#carousel" data-slide-to="7"></li>
