<div id="wins" 
        style="position:absolute;height:200;width:200;overflow:auto;background:#EEEEEE;"> 
        <p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p> 
        <p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p>
