在使用<marquee width="100%" behavior="scroll" direction="left" ></marquee>时，如何让滚动的字幕，连续滚动，不会出现页面某一时刻


不能,只能用程序来实现给你个代码自己看看吧,图片你自己找一个吧
<html>
<head>
<title>Up scroll</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head><body bgcolor="cccccc">      <div id="demo" style="overflow:hidden;height:200;width:96;">
        <div id="demo1" >
          <img src="images/1.gif" width="96" height="96">
          <img src="images/2.gif" width="96" height="96">
          <img src="images/3.gif" width="96" height="96">
        </div>
       <div id="demo2" ></div>
      </div>
      
      <script>
         var speed=30
         
         
         demo2.innerHTML=demo1.innerHTML //克隆demo1为demo2
         function Marquee(){
            if(demo2.offsetTop-demo.scrollTop<=0) //当滚动至demo1与demo2交界时
               demo.scrollTop-=demo1.offsetHeight  //demo跳到最顶端
               
            else{
               demo.scrollTop++
               
            }
            
         }
         var MyMar=setInterval(Marquee,speed) //设置定时器
         demo.onmouseover=function() {clearInterval(MyMar)}//鼠标移上时清除定时器达到滚动停止的目的
         demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}//鼠标移开时重设定时器
         
         
      </script>
