Der Hintergrund wechselt permanent die Farbe
In den <HEAD> schreiben:
<script language="JavaScript">
//<!--
function cycle(){
window.document.bgColor ="#ff0000";
timerID=setTimeout('document.bgColor ="#ff0033"',70);
timerID=setTimeout('document.bgColor ="#ff0066"',140);
timerID=setTimeout('document.bgColor ="#ff0099"',210);
timerID=setTimeout('document.bgColor ="#ff00cc"',280);
timerID=setTimeout('document.bgColor ="#ff00ff"',350);
timerID=setTimeout('document.bgColor ="#ff00cc"',420);
timerID=setTimeout('document.bgColor ="#ff0099"',490);
timerID=setTimeout('document.bgColor ="#ff0066"',560);
timerID=setTimeout('document.bgColor ="#ff0033"',630);
los=setTimeout("cycle()",630);
}
//-->
</script>
Der <BODY.. muß erweitert werden um:
onload="cycle()"
