Question

我正在尝试使用Bootstrap制作用于销售网站的轮播，但似乎并没有启动。

我仔细阅读了代码，所有内容似乎都与他们站点上给出的示例相匹配，但是它看起来就像是四张图像堆叠在一起，另一张堆叠在底部，而上一个和后一个按钮在底部。

在开发人员工具上查看时，单击这些按钮的确会更改各种照片中的active标签，但似乎没有任何视觉效果。

如果这是一个问题，我将遍历数据库图片，但是这些图片似乎在正确的位置出现和显示。干杯。

如果有帮助，请参见以下代码：

<div class="container">
  <div id="carouselExampleIndicators" class="carousel slide pointer-event" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1" class=""></li><li data-target="#carouselExampleIndicators" data-slide-to="2" class=""></li><li data-target="#carouselExampleIndicators" data-slide-to="3" class=""></li>  </ol>
  <div class="carousel-inner">

              <div class="carousel-item active">
              <img src="img/5c93c5fec0d110.10065506.jpg" class="d-block w-100" alt="Absolute Balderdash">
              </div>

          <div class="carousel-item">
            <img src="img/5c93c5fec16a35.12174898.jpg" class="d-block w-100" alt="Absolute Balderdash">
          </div>

          <div class="carousel-item">
            <img src="img/5c93c5fec1c830.06571881.jpg" class="d-block w-100" alt="Absolute Balderdash">
          </div>

          <div class="carousel-item">
            <img src="img/5c93c5fec20b53.10796324.jpg" class="d-block w-100" alt="Absolute Balderdash">
          </div>
            </div>
  <a class="carousel-control-prev" href="#carouselExampleIndicators" 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="#carouselExampleIndicators" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

完全没有错误。您可能需要检查是否必须插入所需的库。
