Bootstrap 4旋转木马组件问题

Bootstrap 4 Carousel component Issue

本文关键字：问题 组件 旋转木马 Bootstrap      更新时间：2024-07-01

我正在尝试将Carousel Bootstrap 4实现到一个个人项目中。我对HTML5、CSS3、Bootstrap 4和JS有基本的了解。我看了一些关于如何使用旋转木马组件的讨论和教程，但无法在浏览器中获得正确的输出。我使用chrome和firefox，在这两种浏览器中都有相同的问题。我已经检查了（链接）和（脚本）的路径，我甚至不得不将（img data src="#"）更改为（img src="#），这样图像才能正确加载到浏览器中。这些图像叠在一起，不知道如何纠正这个问题。我直接从Bootstrap网站复制代码。这是我第一次进入社区，也是我的第一个问题。只是对这个组件感到有点沮丧。

提前感谢！

您需要将HTML放入<body>标记中，以便正确呈现。

<body>
<nav>
</nav>
<section id="carousel">
  <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
    <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="2"></li>
    </ol>
    <div class="carousel-inner" role="listbox">
      <div class="carousel-item active">

将类"carousel item"更改为"item"。
