Text Resizer

This is the code I made for Enchant's forum Enchanted Element (look in the sidebar; meant as an example, not advertising):
<script type="text/javascript">
<!--
// "Change font-size" by Dravu
function changesize(change){
if(change == "normal"){
document.cookie="size=;expires="+new Date().toGMTString()+";";
window.location.reload();
} else {
var tags = new Array('font','div','td');
if(document.cookie.match(/size/)){
var size = document.cookie.split('size=')[1];
size = size.split(';')[0];
} else {
size = 12;
}
if(change == '0' && !document.cookie.match(/size=/)){} else {
change = Math.round(change);
size = Math.round(size);
size = size+change;
if(size>0){
var date = new Date();
date.setTime(date.getTime()+(365*24*60*60*1000));
document.cookie='size='+size+';expires='+date.toGMTString()+';';
for(a=0;a<tags.length;a++){
var tag_num = document.getElementsByTagName(tags[a]);
for(b=0;b<tag_num.length;b++){
tag_num[b].style.fontSize=size+'px';
}
}
}
}
}
}
changesize('0');
//-->
</script>Put that in your global footers and then use the changesize function to make your links. Example:
<a href="javascript:changesize('+2')">Larger</a> |
<a href="javascript:changesize('normal')">Normal</a> |
<a href="javascript:changesize('-2')">Smaller</a>
It increases/decreases by pixel amount instead of font size. If you want it to increase/decrease by 1px at a time instead of two, change the "+2" and "-2" in the links to "+1" and "-1".

Sure. Go ahead an PM me the URL. ^^

Whoops. I made an error when I did a few quick updates when pulling it over. Fixed the code. ^^

This is something i've been looking for, but i'm failing to understand how to use the stuff in the second box.

Can you help me with this as well please?

Ok thanks.

But where do I put the links into the code about?

Shouldn't the changesize function be defined above the links? If someone were to click them before the footer loaded, they'd get an error.

Some people still have slow Internet nowadays. It might take a while before the footer loads.

Instead of putting the links in the footer, they could put the script in the header.
