使用方法

第一步：添加Bootstrap框架

使用Bootstrap carousel轮转图需要先在HTML页面中添加Bootstrap框架，可以通过CDN或者本地文件引入：

<!-- 通过CDN引入Bootstrap框架 -->
<link rel="stylesheet" href="https://cdn.bootcdn.net/ajax/libs/twitter-bootstrap/4.6.0/css/bootstrap.min.css">
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script src="https://cdn.bootcdn.net/ajax/libs/twitter-bootstrap/4.6.0/js/bootstrap.min.js"></script>

第二步：添加轮播组件

在HTML页面中添加轮播组件，设置ID、类和样式等属性。

<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://picsum.photos/id/1/800/400" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://picsum.photos/id/2/800/400" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://picsum.photos/id/3/800/400" class="d-block w-100" alt="...">
    </div>
  </div>
  <a class="carousel-control-prev" href="#carouselExampleControls" 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="#carouselExampleControls" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

第三步：设置属性参数

可以通过设置一些属性参数来实现轮播图的自定义功能，比如：自动播放、轮播间隔时间、滑动响应等。

<div id="carouselExampleControls" class="carousel slide" data-ride="carousel" data-interval="2000">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://picsum.photos/id/1/800/400" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://picsum.photos/id/2/800/400" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://picsum.photos/id/3/800/400" class="d-block w-100" alt="...">
    </div>
  </div>
  <a class="carousel-control-prev" href="#carouselExampleControls" 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="#carouselExampleControls" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

示例说明

  <ol class="carousel-indicators">
    <li data-target="#carouselExampleCaptions" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleCaptions" data-slide-to="1"></li>
    <li data-target="#carouselExampleCaptions" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://picsum.photos/id/1/800/400" class="d-block w-100" alt="...">

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

示例二：轮播响应式布局

<div id="carouselExampleFade" class="carousel slide carousel-fade" data-ride="carousel">
  <div class="carousel-inner">

  </div>
  <a class="carousel-control-prev" href="#carouselExampleFade" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
