Hey @bkenney27,
Thank you for reaching out to us with your question.
The Facebook Like Box that you can enable in our plugin is simply adding the Facebook like box widget. This is an iframe that is created by Facebook and the only options you are able to change, are the ones you see when you click ‘Show Customization Options’ in our plugin, in this case the closest you could get to centering it is the width. You can adjust this slightly by adjust the padding on .cff-likebox, to be something like
.cff-likebox {
padding: 0 5%; // Change 5% to fit your page
}
It is not possible to affect styling neither via CSS nor JS for iframes otherwise. I hope this is useful to you.
Let us know if you have any more questions as we are happy to help.
Many thanks.
