以下例子信息来自http://www.uecss.com/index.php/fixed-floating-imitation-navigation/
页面加入样式:
![](/Images/OutliningIndicators/ExpandedBlockStart.gif)
body {
background-image:url(text.txt); /* for IE6 */
background-attachment:fixed;
}
.bottomNav {
background-color:#096;
z-index:999;
position:fixed;
bottom:0;
left:0;
width:100%;
_position:absolute; /* for IE6 */
_top: expression(documentElement.scrollTop + documentElement.clientHeight-this.offsetHeight); /* for IE6 */
overflow:visible;
}
将要显示的DIV加上
![](/Images/OutliningIndicators/ExpandedBlockStart.gif)
class="bottomNav"
下边这个是原创,也是纯CSS实现:
![](/Images/OutliningIndicators/ExpandedBlockStart.gif)
