<!-- 指示符 -->
<ul class="carousel-indicators">
<li data-target="#demo" data-slide-to="0" class="active"></li>
<li data-target="#demo" data-slide-to="1"></li>
<li data-target="#demo" data-slide-to="2"></li>
</ul>
<!-- 轮播图片 -->
<div class="carousel-inner">
<div class="carousel-item active">
<img src="https://static.NowJava.com/images/mix/img_fjords_wide.jpg">
</div>
<div class="carousel-item">
<img src="https://static.NowJava.com/images/mix/img_nature_wide.jpg">
</div>
<div class="carousel-item">
<img src="https://static.NowJava.com/images/mix/img_mountains_wide.jpg">
</div>
</div>
<!-- 左右切换按钮 -->
<a class="carousel-control-prev" href="#demo" data-slide="prev">
<span class="carousel-control-prev-icon"></span>

<a class="carousel-control-next" href="#demo" data-slide="next">

</a>
