Edit your details - how to change form background?

Greetings, Im having trouble with Edit your details form. I would like to change its background to be transparent, currently with no results. I was able to however change Contact Info tab to transparent but I have had no succes with form background. So how do I do this? Can this be done via com_comprofiler/plugin/templates/default/template.css or is it different .css file? I searched forums but it was no success. I'll provide picture of what i want to change for reference. Im semi-experienced with .css but not so with CB. Appreciate your help, thank you!

I solved it after hours of trying. Found proper setting in

.dynamic-tab-pane-control .tab-page {
clear: both;
border: 1px solid #666;
background: transparent; <--- from color to transparent
z-index: 2;
position: relative;
top: -2px;
color: #ffcc99;
font-family: Message-Box,sans-serif;
width: 100%;
