本文介绍了一种使用HTML、CSS和JavaScript实现的滚动图文展示技术，包括方向向上、向下、向左和向右四种滚动方式。

1.方向向上

<base href="http://www.flash8.net">
<div id=demo style=overflow:hidden;height:100;width:90;background:#214984;color:#ffffff><div id=demo1>
<img src="images/flash8.gif">
<img src="images/link/flashempire.gif">
<img src="images/linklogo/shlogo.gif">
<img src="images/link/deskcity.gif">
<img src="images/linklogo/5dmeng.gif">
<img src="http://www.blueidea.com/logo.gif">
<img src="images/link/flashskylogo.gif">
<img src="images/link/5dlogo88.gif">
<img src="http://www.yiiboo.com/cgercn/link.gif">
</div>
<div id=demo2></div>
</div>
   <script>
   var speed=30
   demo2.innerHTML=demo1.innerHTML
   function Marquee(){
   if(demo2.offsetTop-demo.scrollTop<=0)
   demo.scrollTop-=demo1.offsetHeight
   else{
   demo.scrollTop++
   }
   }
   var MyMar=setInterval(Marquee,speed)
   demo.onmouseover=function() {clearInterval(MyMar)}
   demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
   </script>
2.方向向下

<base href="http://www.flash8.net">
<div id=demo style=overflow:hidden;height:100;width:90;background:#214984;color:#ffffff><div id=demo1>
<img src="images/flash8.gif">

<img src="http://www.yiiboo.com/cgercn/link.gif">
</div>
<div id=demo2></div>
</div>
    <script>
    var speed=30
    demo2.innerHTML=demo1.innerHTML
    demo.scrollTop=demo.scrollHeight
    function Marquee(){
    if(demo1.offsetTop-demo.scrollTop>=0)
    demo.scrollTop+=demo2.offsetHeight
    else{
    demo.scrollTop--
    }
    }
    var MyMar=setInterval(Marquee,speed)
    demo.onmouseover=function() {clearInterval(MyMar)}
    demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
    </script>
3.方向向左

<base href="http://www.flash8.net">
<div id=demo style=overflow:hidden;height:33;width:500;background:#214984;color:#ffffff><table align=left cellpadding=0 cellspace=0 border=0><tr><td id=demo1 valign=top><img src="images/link/flashempire.gif"><img src="images/linklogo/shlogo.gif"><img src="images/link/deskcity.gif"><img src="images/linklogo/5dmeng.gif"><img src="http://www.blueidea.com/logo.gif"><img src="images/link/flashskylogo.gif"><img src="images/link/5dlogo88.gif"><img src="http://www.yiiboo.com/cgercn/link.gif"><img src="images/flash8.gif"></td><td id=demo2 valign=top></td></tr></table></div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
4.方向向右

<base href="http://www.flash8.net">
<div id=demo style=overflow:hidden;height:33;width:500;background:#214984;color:#ffffff><table align=left cellpadding=0 cellspace=0 border=0><tr><td id=demo1 valign=top><img src="images/link/flashempire.gif"><img src="images/linklogo/shlogo.gif"><img src="images/link/deskcity.gif"><img src="images/linklogo/5dmeng.gif"><img src="http://www.blueidea.com/logo.gif"><img src="images/link/flashskylogo.gif"><img src="images/link/5dlogo88.gif"><img src="http://www.yiiboo.com/cgercn/link.gif"><img src="images/flash8.gif"></td><td id=demo2 valign=top></td></tr></table></div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
demo.scrollLeft=demo.scrollWidth
function Marquee(){
if(demo.scrollLeft<=0)
demo.scrollLeft+=demo2.offsetWidth
else{
demo.scrollLeft--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
