how to change the design of pop-up

We have a complete theming system for the SCLogin module. With that, you're free to modify the complete looks of the SCLogin module however you want. For more information on how to edit the output, see our SCLogin Theming Guide .

We can't style things for you as every site is different, and we aren't template designers to begin with, but I hope that helps get you going.

Thanks,
Alex

I also wanted to point out that the buttons you have in your existing modal popup are not going to work. They look to be put there by another extension or, if you've done them yourself, they are not calling JFBConnect properly.
