ændre font, farve og størrelse

Jeg har et script der viser dato og tid, men jeg ønsker at kunne ændre på størrelsen, fonten og farven.

Det skulle vist være rimelig simpelt?

<SCRIPT LANGUAGE = \"JavaScript\">
var dayarray = new Array(\"Sunday\", \"Monday\", \"Tuesday\", \"Wednesday\",
\"Thursday\", \"Friday\", \"Saturday\");
var montharray = new Array(\"January\", \"February\", \"March\", \"April\", \"May\",
\"June\", \"July\", \"August\", \"September\", \"October\", \"November\", \"December\");
var now = new Date();
var myyear = now.getYear();
var mymonth = now.getMonth();
var myday = now.getDay();
var mydate = now.getDate();
var myhour = now.getHours()
var myminute = now.getMinutes()
var mysecond = now.getSeconds()
if (myyear < 1000){myyear += 1900};
if (myhour>=12){mymidday=\"pm\" } else {mymidday=\"am\"}
if (myhour>12) {myhour = myhour -12 }
if (myhour==0) { myhour=12 }
if (myhour<10) { myhour=\"0\"+myhour }
if (myminute<10) { myminute=\"0\"+myminute }
if (mysecond<10) {mysecond=\"0\" + mysecond}
var timetext = dayarray[myday];
timetext += \", \" + montharray[mymonth];
timetext += \" \" + mydate;
timetext += \" \" + myyear;
timetext += \", \" + myhour;
timetext += \":\" + myminute;
timetext += \":\" + mysecond;
timetext += mymidday;
document.write(timetext);
</SCRIPT>
