Dear nextideas!
i have not a clear understanding on the issue.
You can see the cufon applying some rules as folowing:
<script type=”text/javascript”>
Cufon.replace(‘.componentheading, .contentheading, div.moduletable h3, div.moduletable_menu h3, div.moduletable_text h3,div.moduletable_highlight h3’, { fontFamily: ‘HelveticaRounded’ });
</script>
(note: above codes are put in the templates/JA Beryl/index.php file).
You can see the css rules in the template.css file you ‘ll change font-size of them in css rules you would like. when you change theirs font-size then the font-size of cufon will be changed.
