Hello, I try to use suffix with categories module of Virtuemart. If I use LIGHT the words appears with underline and this is right, but the backgound colour is not gray as is in your example of suffix LIGHT in your Demo template. I will like that the background colour be different than the white. See this link to your example: https://demo.gavick.com/joomla25/instyle/index.php/template/template-features/module-variations
