function frame() {
top=(top>rest)?rest:(top+1);
left=(left>resl)?resl:(left+1);
        document.getElementById("ger").style.top = top + "px";
        document.getElementById("ger").style.left = left + "px";
        if ( (top >= rest) && (left>=resl) ) {  
        clearInterval(timer);
            }
    }
    var timer = setInterval(frame, 10);
