<h1>jQuery Scrolling Background with Randomised Overlay Effect Demos</h1>
<h6>jquery背景滚动特效演示</h6>
<h3>示例 1</h3>
<div id="container">
    <div id="overlay" class="png-fix">
         <div id="title">
              ooh,<br />pretty.
         </div>
    </div>
</div>
<p>Notice how the background slowly changes colour over time. Refresh the page a few times - you will see that the overlaid image moves around as well. This creates a unique effect on every page load, meaning that you will never have exactly the same design element twice. Leave us a comment to show how you have implemented this effect into your designs - we'd love to see how creative you have got!</p>
<br />
<h3>示例 2</h3>
<p>The below effect was achieved by adding a third div inside the 'id="overlay"' containing div. Giving it absolute positioning as well means you can then use a transparent png image in the foreground of this third div. Obviously, being transparent, you can see through certain areas of this .png and on to the background we have created. </p>

jQuery随机的网页背景滚动效果

描述

jQuery+pngFix.js共同实现绚丽的网页背景滚动效果，一共两个例子演示，第一个是大背景+文字，可看到背景内的元素在不断的慢慢滚动，气泡升腾的效果；第二种是纯背景，无文字。这两种最常用了，这款背景效果除了这样用之外，还可以用在图...
