<html><head>  <title></title></head><body>  <div style="height:960px;background:#330000;">teatteat</div>  <div id="t" style="height:24px;background:#000000;color:#ffffff;text-align:center;">teatteat</div>  <div style="height:960px;background:#333333;">teatteat</div><script type="text/javascript">document.body.onscroll=function(){  if(document.body.scrollTop>=document.getElementById("t").offsetTop){    document.getElementById("t").style.position="absolute";    document.getElementById("t").style.top=document.body.scrollTop;  } else {    document.getElementById("t").style.position="static";    document.getElementById("t").style.top=document.body.scrollTop;  }} </script></body></html>
