Bueno veamos , el primero es muy simple solo se cambia los valores left y top de la capa :
Código PHP:
<html>
<head>
<body>
<script language="JavaScript1.2">
var delay=3000 //pausa (en milisegundos)
var fcontent=new Array()
begintag='<font face="Arial" size=2>' //tag que abre los mensajes
fcontent[0]="<b>Ejemplo...</b><br><br>Crear un sitio web es relativamente fácil. Lo dificil es darle un buen contenido, diseño y enfoque"
fcontent[1]="El tener en un mismo sitio, mas de 3 paginas de informacion, cansa al visitante y lo hace dejar el sitio."
fcontent[2]="Una de las causas por las que el visitante regresa a un sitio frecuentemente es porque bla, bla, bla."
closetag='</font>'
var fwidth=150 //ancho
var fheight=150 //alto
///No editar/////////////////
var ie4=document.all&&!document.getElementById
var ns4=document.layers
var DOM2=document.getElementById
var faderdelay=0
var index=0
if (DOM2)
faderdelay=2000
//function to change content
function changecontent(){
if (index>=fcontent.length)
index=0
if (DOM2){
document.getElementById("fscroller").style.color="rgb(255,255,255)"
document.getElementById("fscroller").innerHTML=begintag+fcontent[index]+closetag
colorfade()
}
else if (ie4)
document.all.fscroller.innerHTML=begintag+fcontent[index]+closetag
else if (ns4){
document.fscrollerns.document.fscrollerns_sub.document.write(begintag+fcontent[index]+closetag)
document.fscrollerns.document.fscrollerns_sub.document.close()
}
index++
setTimeout("changecontent()",delay+faderdelay)
}
// colorfade() partially by Marcio Galli for Netscape Communications. ////////////
frame=20;
hex=255 // Initial color value.
function colorfade() {
// 20 frames fading process
if(frame>0) {
hex-=12; // increase color value
document.getElementById("fscroller").style.color="rgb("+hex+","+hex+","+hex+")"; // Set color value.
frame--;
setTimeout("colorfade()",20);
}
else{
document.getElementById("fscroller").style.color="rgb(0,0,0)";
frame=20;
hex=255
}
}
if (ie4||DOM2)
document.write('<div id="fscroller" style="position:absolute;left:300px;top:150px;border:1px solid black;width:'+fwidth+';height:'+fheight+';padding:2px"></div>')
window.onload=changecontent
</script>
<ilayer id="fscrollerns" width=&{fwidth}; height=&{fheight};><layer id="fscrollerns_sub" width=&{fwidth}; height=&{fheight}; left=0 top=0></layer></ilayer>
</body>
</html>
ahora el segundo , ese si que es un problema , utiliza muchas funciones matematicas , y encontrar el valor exacto es mas trabajoso... pero bueno estoy osioso hoy asi que aqui va :
Código PHP:
<html>
<body bgcolor="#ffffff" scroll="no">
<script>
<!-- // Hide
var isDOM = false, isNS4 = false;
if (document.all) var isDOM = true, docObj = 'document.all.', styObj = '.style';
else if (document.layers) var isNS4 = true, docObj = 'document.', styObj = '';
var quotes = new Array(); c = 0;

}

}
setInterval('checkDivs()', 50);
}
if (isDOM || isNS4) initDivs();
// End Hide -->
</script>
</body>
</html>
solo cambie el valor maximo del ancho de las capas y la distancia del borde superior..
