jQuery Style Sheet (CSS) Switcher

I have been looking for a nifty style-switching script, and have found none. So here is the code for a checkbox-based style switcher. This uses jQuery.

The Javascript:

/*ChangeStyle.js:
* -by Skaman Sam Tyler - http://rbe.homeip.net
*
* This script uses checkboxes to add and remove stylesheets from the page.
* It takes the value of the 'rel' attribute from the checkbox and creates a stylesheet link with it.
* */

if ($) {    //check for jQuery

  //on document load, uncheck all checked boxes and add function handler for
  $(document).ready( function() {
    $('.styleToggle').removeAttr("checked");    //uncheck all checked
    $('.styleToggle').click( function() {        //add handler for clicking
      toggleStyle(this.getAttribute("rel"));
      return true;
    });
});

//the toggling of the style. it takes a single parameter: the href of the stylesheet to toggle
function toggleStyle(href) {

  //check for presence of link, if it exists, delete it, else, add it.
  if($('link[href*='+href+']').size()!=0){
    $('link[href*='+href+']').remove();
  }else{
    console.log("Adding: "+$('link[href*='+href+']'));
    $('head').append('<link rel="stylesheet" href="'+href+'" type="text/css" media="screen" />');
  }
}
}

The HTML file should include something like this:

<form name="styleSwitchForm">
<ul>
<li><label><input type="checkbox" rel="/styles/red.css" class="styleToggle"/> Red Style</label></li>
<li><label><input type="checkbox" rel="/styles/blue.css" class="styleToggle"/> Blue Style</label></li>
<li><label><input type="checkbox" rel="/styles/green.css" class="styleToggle"/> Green Style</label></li>
</ul>
</form>
