carousel 是 layui 2.0 版本中新增的全新模块，主要适用于跑马灯/轮播等交互场景。它并非单纯地为焦点图而生，准确地说，它可以满足任何类型内容的轮播式切换操作，更可以胜任 FullPage （全屏上下轮播）的需求，简洁而不失强劲，灵活而优雅。

<p>
在HTML结构中，只需要简单地注意这两项：
<br>1) 外层元素的 <em>class="layui-carousel"</em> 用来标识为一个轮播容器
<br>2) 内层元素的属性 <em>carousel-item</em> 用来标识条目
</p>
<p>而 <em>id</em> 则用于carousel模块建造实例的元素指向，剩下的工作，就是按照你的实际需求，给方法设置不同的基础参数了。</p>

<fieldset class="layui-elem-field layui-field-title site-title">
<legend><a name="options">基础参数选项</a></legend>
</fieldset>
<div class="site-text">
<p>通过核心方法：<em>carousel.render(options)</em> 来对轮播设置基础参数，也可以通过方法：<em>carousel.set(options)</em> 来设定全局基础参数.</p>
