The new website could use a bigger font so it's easier to read.
Does anyone know how to make the JavaScript, CSS font size selector you see on some websites? You know the small a, bigger a, big a (small, medium or large font size)?

You could try something like:
<html> <body> <a onclick="document.body.style.fontSize='1em';">1</a> <a onclick="document.body.style.fontSize='2em';">2</a> <a onclick="document.body.style.fontSize='3em';">3</a> </body> </html>

Do you know how to make this persist via a user cookie set from javascript/read from javascript?

Let's try (this is untested):
// Borrowed from http://www.w3schools.com/JS/js_cookies.asp
function setCookie(c_name,value,expiredays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate()+expiredays);
document.cookie=c_name+ "=" +escape(value)+
((expiredays==null) ? "" : ";expires="+exdate.toGMTString());
}
function getCookie(c_name)
{
if (document.cookie.length>0)
{
c_start=document.cookie.indexOf(c_name + "=");
if (c_start!=-1)
{
c_start=c_start + c_name.length+1;
c_end=document.cookie.indexOf(";",c_start);
if (c_end==-1) c_end=document.cookie.length;
return unescape(document.cookie.substring(c_start,c_end));
}
}
return "";
}
Now you need to add to body onload="" event a call to get the size set in the cookie and modify our change font function so...
<html>
<body onload="javscript: restoreEUFontSize();">
<a onclick="javascript: storeEUFontSize('1');">1</a>
<a onclick="javascript: storeEUFontSize('1');">2</a>
<a onclick="javascript: storeEUFontSize('1');">3</a>
</body>
</html>
function setEUFontSize(fsize) {
document.body.style.fontSize=fsize+'em';
}
function storeEUFontSize(fsize)
{
setCookie('eu4FontSize',fsize,90);
setEUFontSize(fsize);
}
function restoreEUFontSize() {
var fsize = getCookie('eu4FontSize');
if (fsize == '')
return;
setEUFontSize(fsize);
}
Edit: Fixed a typo
