CSS Help

Hi There,

I have just been taking a look at the Facebook Tabs Manager Plugin. I have created a page with the shortcode [mp_list_global_products]. Cool it works, but looks bad, have a look: http://fondelifair.com/blog/fbtab/market/ There looks like there is no css there at all. I have tried using the css from my theme in the settings, though that made no change. Could you tell me how to make it look pretty? Just like it appears in the theme would be good. Here it is on my site: http://fondelifair.com/marketplace

Thank you.
