Once the font size is selected, a cookie is set. The next time the user comes to the page the font will be the same size they left it.

Example:

JAVASCRIPT

function $(v) { return(document.getElementById(v)); }
function cookieStab(f,v) { document.cookie=f+'='+v+'; path=/'; }
function cookieGrab(f) { var c=document.cookie.split(';'); f=f+"="; for(var i in c) { var v=trim(c[i]); if(v.indexOf(f)==0) { return(v.substr(f.length,v.length)); } } }
function mkStyle(v,s) { v=zero(v); if(v) { var b=!s?(zero($('test').style.fontSize)+v):v; $('test').style.fontSize=b+'px'; cookieStab('fontSize',b); } }
function trim(v) { return(v.replace(/(?:(?:^|\n)\s+|\s+(?:$|\n))/g,"")); }
function zero(v) { v=parseInt(v); return(!isNaN(v)?v:0); }

window.onload=function() { mkStyle(cookieGrab('fontSize'),1); };

HTML

<div id="test">
 <a href="#" onclick="mkStyle(1); return false;" title="increase font size">larger</a>
 <a href="#" onclick="mkStyle(-1); return false;" title="decrease font size">smaller</a>
</div>
