Change css-class of module?

Hello

So I've installed joomla-visites and it's working fine.
However I have something that bothers me:
As I have to display it on the site and there's no content I get an empty box (due to the css class)

So is there a way to change the css class of the module? (like on other mods you can add a suffix)

Thanks in advance

Hi,

you can edit the css-file of Joomla-Visites in /administrator/components/com_joomla-visites/themes/default/css/styles.php
