首页banner的酷炫效果多来自全屏大图的幻灯片动画，下面提供一种完美兼容的jquery动画特效：全新jquery多点滑动幻灯片——全屏动画animateSlide（代码完全原创）。
直接上代码，把html、css和jquery代码copy到页面上即可呈现完美画面。
html代码如下：

<!--<img class="img" alt="" src="img/1.png" />-->
<div class="img" style="width: 500px; height: 390px; background: #ffaeae; opacity: 0.6;"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->
</div>
<div class="animateSlideImgBox">
