//     JQuery Text resize + Cookie recall
//     Ben Hayes, January 2010 | info@jackfruitdesign.com
//     Based initially on a script from http://www.shopdev.co.uk/blog/text-resizing-with-jquery/
//     This script gives a simplified binary option: normal or large text

$(document).ready(function() {

    // declare a few constants:
    var SMALL = 1.0; //small font size in pixels
    var MEDIUM = 1.3;
    var LARGE = 1.5; //larger size in pixels
    var COOKIE_NAME = "CourageCenter-Fontresizer"; //Maybe give this the name of your site.

    //make it small by default
    var fontsize = SMALL;

    // Only show text resizing links if JS is enabled
    $(".fontresize").show();

    // if cookie exists set font size to saved value, otherwise create cookie
    if ($.cookie(COOKIE_NAME)) {
