Sorry to bug you but I have been struggling with removing the border. I'm a total newb to this.
I used the Plugin editor to remove the border by erasing the border section completely...
#fancybox-content {
width: 0;
height: 0;
padding: 0;
outline: none;
position: relative;
overflow: hidden;
z-index: 110002;
(removed this) border: 0px solid #fff;
}
The border went away but has replaced it with a thicker white line on the right side of the picture. Obviously what I tried can't work.
Could you explain where you went to add the info you provided? The name of the file would be helpful.
