How to: Enlarge text in a specific css class

[Zacharicus]

What's the best way to setup a button on a website that tells spesific css classes to enlarge the font size by a certain percentage?

Basically, on this html/css site, the user should be able to enlarge the font sizes, but not all, only the main content texts, not all the others, so I need to specify certain classes.

Any help would be appreciated. Thanks.

One way can be...

hmm you can use php or some other language to do this..

it can be done like this...

Add css code in the page

give conditions like this

<?php
if ($option == "1")
{
$set_size = "12px";
}

if ($option == "2")
{
$set_size = "14px";
}

if ($option == "3")
{
$set_size = "16px";
}
else
{
$set_size = "10px";
}
?>

<style>
.content {font-size:<?php $set_size; ?>;}
</style>

now pass option value from the query string first and then you can store it in cookie so you dont needs to pass it from query string all the time..

I hope you got what i said..
