I am not completely inexperienced, but I cant figure out how to change the overlay factor in the Firm theme for the zoom box.I found the code to be originated in the theme-shortcodes.php file: 
				$output .= '<div class="desc" style="background-color:'. hex2rgba( $bg_color, 0.8 ) .';">';
I want to change the overlay factor to 0.95
I dont want to edit the php file. Can I use the Custom | Classes in column to accomplish this? How?

.zoom_box a .desc {background:rgba(0,0,0,.95) !important;
}
