<link rel="stylesheet" type="text/css" href="<?php echo TEMPLATE_DIR; ?>/default.css" media="all" />
<script type="text/javascript" src="<?php echo WB_URL;?>/include/jquery/jquery-min.js"></script>
<script type="text/javascript" src="<?php echo TEMPLATE_DIR;?>/jquery.jfontsizer.min.js"></script>
and
<script type="text/javascript">
$(document).ready(function(){
$('#fontsizer').jfontsizer({
applyTo: '.content',
changesmall: '3',
changelarge: '6',
expire: 30
});
});
</script>
body
<div id="fontsizer"></div>
