Transparent background on lightboxes


Hey guys!

I wanna know if u can help me on transparent backgrounds for my lightboxes. As you can see on the link i’ve showed u, i want to display only the circle that contains the form, without that white square behind it. i made a few tests and tried to attach a css style on the section class, but it resulted in a white page and everything disappeared.

here is the code i added:

.lp-pom-block { background-color: transparent; } **and the the lightbox im talking about:** Can anyone help me on this code? Thanks in advance!
