这篇文章主要介绍了一款非常酷炫的jQuery全屏3D焦点图动画效果其特点是整个焦点图基本是全屏显示的，非常大气，感兴趣的小伙伴们可以参考一下

HTML代码：

<div class="wrapper">

</div>

<div id="pxs_container" class="pxs_container">

 <div class="pxs_bg">

 <div class="pxs_bg1"></div>

 <div class="pxs_bg2"></div>

 <div class="pxs_bg3"></div>

 </div>

 <div class="pxs_loading">Loading images...</div>

 <div class="pxs_slider_wrapper">

 <ul class="pxs_slider">

  <li><img src="images/1.jpg" alt="First Image" /></li>

  <li><img src="images/2.jpg" alt="Second Image" /></li>

  <li><img src="images/3.jpg" alt="Third Image" /></li>

  <li><img src="images/4.jpg" alt="Forth Image" /></li>

  <li><img src="images/5.jpg" alt="Fifth Image" /></li>

  <li><img src="images/6.jpg" alt="Sixth Image" /></li>

 </ul>

 <div class="pxs_navigation">

  <span class="pxs_next"></span>

  <span class="pxs_prev"></span>

 </div>

 <ul class="pxs_thumbnails">

  <li><img src="images/thumbs/1.jpg" alt="First Image" /></li>

  <li><img src="images/thumbs/2.jpg" alt="Second Image" /></li>

  <li><img src="images/thumbs/3.jpg" alt="Third Image" /></li>

  <li><img src="images/thumbs/4.jpg" alt="Forth Image" /></li>

调用插件的JavaScript代码

$(function() {

 var $pxs_container = $('#pxs_container');

 $pxs_container.parallaxSlider();

});
