基于jQuery制作企业家具网站首页banner响应式图片轮播，支持带左右按钮控制图片淡出淡现切换效果。手机自适应屏幕大小。修改：添加json动态数据轮播图片。

使用方法

1、head引入css文件

<link rel="stylesheet" href="css/style.css" />

2、head引入js文件

<script type="text/javascript" src="js/jquery.min.js"></script>

3、body引入HTML代码

<div class="c-banner">
	<div class="banner">
		<ul>
			<li><img src="img/lunbo1.jpg"></li>
			<li><img src="img/lunbo2.jpg"></li>
			<li><img src="img/lunbo3.jpg"></li>
		</ul>
	</div>
	<div class="nexImg">
		<img src="img/nexImg.png" />
	</div>
	<div class="preImg">
		<img src="img/preImg.png" />
	</div>
	<div class="jumpBtn">
		<ul>
			<li jumpImg="0"></li>
			<li jumpImg="1"></li>
			<li jumpImg="2"></li>
		</ul>
	</div>
</div>

<script type="text/javascript">
