First: Never resize my browser, it's very annoying.
Second: create the drop box, and if the user selects something set a cookie. Then check if the cookie is set if so use the value to load a different css file from the system.
<?php
if (isset($HTTP_POST_VARS["css_id"]) {
setcookie("css_id", $HTTP_POST_VARS["css_id"]);
}
if (!isset($css_id)) $css_id = 1;
switch($css_id) {
case 1:
include "css_file1.css";
break;
case 2:
include "css_file2.css";
break;
default:
include "css_file1.css";
break;
}
?>
That's all there is to it, just make your form submit to the same page, and have this script at the top.
