我从 getbootstrap.com 复制粘贴的轮播代码并更改了 id。然而它仍然不起作用。我想知道我哪里做错了，我应该改正什么？
<div class="py-5">
<div class="container">
<div id="slide" class="carousel slide">
<div class="carousel-indicators">
<button type="button" data-bs-target="#slide" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
<button type="button" data-bs-target="#slide" data-bs-slide-to="1" aria-label="Slide 2"></button>
<button type="button" data-bs-target="#slide" data-bs-slide-to="2" aria-label="Slide 3"></button>
</div>
<div class="carousel-inner">
<div class="carousel-item active" style="background: url(1.jpeg); height: 600px; background-size: cover">
<img src="" class="d-block w-100" alt="slide 1">
</div>
<div class="carousel-item" style="background: url(2.jpeg); height: 600px; background-size: cover">
<img src="" class="d-block w-100" alt="slide 2">
</div>
<div class="carousel-item" style="background: url(3.jpeg); height: 600px; background-size: cover">
<img src="" class="d-block w-100" alt="slide 3">
</div>
</div>
<button class="carousel-control-prev" type="button" data-bs-target="#slide" 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="#slide" data-bs-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
</button>
</div>
</div>
</div>
<script src="js/bootstrap.bundle.js"></script>
您需要使用 CDN 添加 bootstrap JS 和 Bootstrap CSS。您还需要添加图像 src，请参阅下面的示例
<!DOCTYPE html>
