bootstrap实现选项卡
前端的实现选项卡，一共包括三部分首页、垃圾分类、关于作者。使用轮播图实现
在HTML中创建选项卡的框架，包括选项卡的标题和内容。使用Bootstrap的Tab组件可以实现
<ul class="nav nav-tabs">
<li class="active"><a data-toggle="tab" href="#home">首页</a></li>
<li><a data-toggle="tab" href="#garbage">垃圾分类</a></li>
<li><a data-toggle="tab" href="#about">关于作者</a></li>
</ul>
<div class="tab-content">
<div id="home" class="tab-pane fade in active">
<h3>首页</h3>
<p>这里是首页的内容。</p>
</div>
<div id="garbage" class="tab-pane fade">
<h3>垃圾分类</h3>
<p>这里是垃圾分类的内容。</p>
</div>
<div id="about" class="tab-pane fade">
<h3>关于作者</h3>
<p>这里是关于作者的内容。</p>
</div>
</div>
然后，在JavaScript中添加轮播图的代码。使用Bootstrap的Carousel组件可以实现：
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<!-- 指示符 -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
</ol>
<!-- 轮播图片 -->
<div class="carousel-inner">
<div class="item active">
<img src="img/slide1.jpg" alt="轮播图1">
<div class="carousel-caption">
<h3>轮播图1标题</h3>
<p>轮播图1描述</p>
</div>
</div>
<div class="item">
<img src="img/slide2.jpg" alt="轮播图2">
<div class="carousel-caption">
<h3>轮播图2标题</h3>
<p>轮播图2描述</p>
</div>
</div>
<div class="item">
<img src="img/slide3.jpg" alt="轮播图3">
<div class="carousel-caption">
<h3>轮播图3标题</h3>
<p>轮播图3描述</p>
</div>
</div>
</div>
<!-- 左右切换按钮 -->
<a class="left carousel-control" href="#myCarousel" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#myCarousel" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
其中，data-ride="carousel"表示自动播放轮播图，carousel-indicators表示指示符，carousel-inner表示轮播图片，carousel-caption表示轮播图的标题和描述，left carousel-control和right carousel-control表示
保存下面的代码到html文件，直接执行就能得到你要的效果
