If you just want the background to become transparent:
Open Page Takeover
Click Background
Click Select Color
Change #2c3644 into rgba(0, 0, 0, 0.7);
Yes you can.
Open Plugins .. Editor .. page-takeover/css/page-takeover.css
Find the line that starts with .page-takeover-overlay{
Insert .page-takeover-overlay{display:block;opacity:0.9;float:left
