经典炫酷的HTML5/jQuery动画应用示例及源码

jQuery是一款普遍受前端开发者欢迎的Javascript框架，但是开发者貌似更关注jQuery开发的插件，海量的jQuery插件让前端开发者非常方便。HTML5的加入让jQuery这个家族更加丰富多彩，因为利用HTML5，我们可以制作更加绚丽动感的动画特效，HTML5结合jQuery，真是我们开发者的福利啊。本文分享了一些经典炫酷的HTML5/jQuery动画应用，喜欢的朋友可以分享和收藏。

jquery视差滑块幻灯特效

很传统的一款jQuery焦点图插件，但是该焦点图插件是宽屏的，整体看起来非常大气。

核心jQuery代码：

    var oImgBox = getByClass(document.body,'pxs_slider_wrapper')[0];
    var oImg = getByClass(document.body,'pxs_slider')[0];
    var aLi = oImg.getElementsByTagName('li');
    var aImg = oImg.getElementsByTagName('img');

    //各种背景
    var bg1 = getByClass(document.body,'pxs_bg1')[0];
    var bg2 = getByClass(document.body,'pxs_bg2')[0];
