Background Image

Hello

I am adding a full screen image on one of my pages and then the registration form/table over the image. When I do this, the form/table doesn’t show any transparent gaps between the input fields. So the table just looks like one white solid block.

Is there anyway I can have a background image sitting behind the registration form/table and make it so the form field labels are transparent so there are gaps between the form input fields and the form label fields?
