jQuery是一款普遍受前端開發者歡迎的Javascript框架，但是開發者貌似更關注jQuery開發的插件，海量的jQuery插件讓前端開發者非常方便。HTML5的加入讓jQuery這個家族更加豐富多彩，因為利用HTML5，我們可以制作更加絢麗動感的動畫特效，HTML5結合jQuery，真是我們開發者的福利啊。本文分享了一些經典炫酷的HTML5/jQuery動畫應用，喜歡的朋友可以分享和收藏。

jquery視差滑塊幻燈特效

很傳統的一款jQuery焦點圖插件，但是該焦點圖插件是寬屏的，整體看起來非常大氣。

核心jQuery代碼：

    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');
    
    //各種背景
