Combine GK CSS JOMSOCIAL TEMPLATE

Hi,

I'm badly trying to combine the following css files and no matter the way I try it always break !!


gk_style.reset.css
gk_style.toolbar.css
gk_style.layout.css
gk_style.stream.css
gk_style.messaging.css
gk_style.old.css
gk_style.window.css
gk_style.themefix.css

Do you have an idea on how / which file I can combine ?

Thanks.

Just an info : I've tried many ways, included Minify and that always break ! I'm sure there is a way to combine/merge thoses files but something is wrong somewhere..
