DEMO:
- DHTML is the combination of HTML, JavaScript, and CSS
- DOM stands for Document Object Model
- DHTML allows content on a page to change on the fly, without reloading the page
- CSS allows for the separation between content definition and formatting
- CSS stands for Cascading style sheet
- ruanchen provides free, cut and paste DHTML scripts

把代码放入BODY区域便可：
<script type="text/javascript">
iens6=document.all||document.getElementById
ns4=document.layers
//指定滚动速度 (数字大就越快)
var speed=5
if (iens6){
document.write('<div id="container" style="position:relative;width:175px;height:160px;border:1px solid black;overflow:hidden">')
document.write('<div id="content" style="position:absolute;width:170px;left:0;top:0">')
}
</script>
<ilayer name="nscontainer" width=175 height=160 clip="0,0,175,160">
<layer name="nscontent" width=175 height=160 visibility=hidden>
