how to use plugin facebox

Hi everyone,
I would like to create an effect related to this one :
go to http://labs.revyver.com/ then clik on a icone
a new panel pop up, including html/css file
It seems that the webmaster uses the plugin facebox for Jquery
In a nutshell, I would like to open a remote html/css file with the index remaining in the background
Can someone explain me how to use this plugin please !
I've found some doc on the web, but it's hard for me

ps: I don't know javascript nor jquery language ( i know html/css/php and i can use swichmax 2)

ps 2: I'm french, sorry for my bad english

cheers !
Best Regards
