CSS

Hello, 🙂
I just uploaded your plug whos’s really great!

I would just like a little boost/help, to tell me that it css code I can put in my “theme settings” to have the button of my formular, centered… please
I tried with firebug but with “! Important” my action does not work.
(Wrong for my English)
