After visiting any

After visiting any of our posts for 5 seconds, a pop-up box appears to ask people to like our facebook page. here is an example of a post: http://www.encapo.com/internets-going-crazy-new-way-cut-pineapple/

Can you tell me how to center the blue Facebook "like" button? Also, can you tell me how to remove some of the blank white space beneath the title "Want To Be In The Know?"

Thanks for your help!
