为什么我的 bootstrap carousel 滑块不能移动？

编程问答 2022-05-14

问题描述

大家好，我正在尝试通过仅复制代码而不更改任何内容来使用 Bootstrap 中的轮播，但由于某种原因轮播不起作用（无法移至下一张幻灯片）。有谁知道如何解决这个问题？而且，有谁知道如何使轮播尺寸更小？提前致谢。

这是我的代码：

解决方法

你可以试试这个：

<!doctype html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width,initial-scale=1">

    <!-- Bootstrap CSS -->
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-eOJMYsd53ii+scO/bJGFsiCZc+5NDVN2yr8+0RDqr0Ql0h+rP48ckxlpbzKgwra6" crossorigin="anonymous">

    <title>Hello,world!</title>
  </head>
  <body>
<div id="carouselExampleControls" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://images.pexels.com/photos/540518/pexels-photo-540518.jpeg" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://images.pexels.com/photos/540518/pexels-photo-540518.jpeg" class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="https://images.pexels.com/photos/540518/pexels-photo-540518.jpeg" class="d-block w-100" alt="...">
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleControls" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleControls" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>

    <!-- Option 1: Bootstrap Bundle with Popper -->
