Sorry first one had no spaces.
Hi made a little plugin that handles resizing the font on a page. Only thing
it relies on is that you have fonts set by em on your page. The plugin
requires jquery and the cookies plugin.Feedback would be appreciated.
Cheers...
To use simply Initialise it like so:
$(document).ready(function() {
var options = { min: -1, max: 2};
//Initialize the font sizer for the site.
$.FontSizer.Init(options);
});
CODE
--------------------------------------------------
/**
* Purpose: Font sizer class, handles increasing and decreasing
font size
of a page.
* It increases the font in 10% increments. By getting the
level / 10 + 1.
i.e. level 2 is .2 + 1 so 1.2 or 120%.
*
* Requires: JQuery and the JQuery cookies plugin.
*
* Use: Setup the fontsizer $.FontSizer.Init(options); the two options
are
min and max, for the min level and max level.
* Defaults are min: -3 and max: 5.

$.FontSizer = {
level: 0,
options : {
min: -3,
max: 5
},
Init : function(options) {
if(options)
$.FontSizer.options = $.extend($.FontSizer.options,
options);
//Get the current level from cookies.
var level = ($.cookie('font_level') != null) ?
$.cookie('font_level') : 0;
//Set the font size to the current leve.
$.FontSizer.SetFontSize(level);
},
IncreaseFontSize : function() {
if(($.FontSizer.level) + 1 <= $.FontSizer.options.max) {
//If we have not exceded the max level,
//Get the next level and the set the size to this level.
var next = (parseInt($.FontSizer.level) + 1);
$.FontSizer.SetFontSize(next);
}
},
DecreaseFontSize : function() {
if(($.FontSizer.level - 1) >= $.FontSizer.options.min) {
//If we have not exceded the min level,
//Get the next level and the set the size to this level.
var next = (parseInt($.FontSizer.level) - 1);
$.FontSizer.SetFontSize(next);
}
},
SetFontSize: function(level) {
//Set the current level in the member variable and the cookie.
$.FontSizer.level = level;
$.cookie('font_level', level);
//Work out the new em value and set it.
var level = (level / 10) + 1;
$("body").css("fontSize", level+"em");
