如何创建旋转木马
下例显示了如何创建带有指示器和控件的基本轮播：
示例代码：
<!-- 轮播 -->
<div id="demo" class="carousel slide" data-bs-ride="carousel">
<!-- 指标/点 -->
<div class="carousel-indicators">
<button type="button" data-bs-target="#demo" data-bs-slide-to="0" class="active"></button>
<button type="button" data-bs-target="#demo" data-bs-slide-to="1"></button>
<button type="button" data-bs-target="#demo" data-bs-slide-to="2"></button>
</div>
<!-- 幻灯片/轮播 -->
<div class="carousel-inner">
<div class="carousel-item active">
<img src="la.jpg" alt="Los Angeles" class="d-block w-100">
</div>
<div class="carousel-item">
<img src="chicago.jpg" alt="Chicago" class="d-block w-100">
</div>
<div class="carousel-item">
<img src="ny.jpg" alt="New York" class="d-block w-100">
</div>
</div>
<!-- 左右控件/图标 -->
<button class="carousel-control-prev" type="button" data-bs-target="#demo" data-bs-slide="prev">
<span class="carousel-control-prev-icon"></span>
</button>
<button class="carousel-control-next" type="button" data-bs-target="#demo" data-bs-slide="next">
<span class="carousel-control-next-icon"></span>
</button>
