Hi, i just created a new site based around the use of nectar flip boxes, they are working well, but id like to add a colored border on the edge of each box to add to the looks of the site, how can i add an individual color to each box on my site? Also i used the background color overlay effect, and when i used border radius for rounded corners it only does the flip box background image and not the background overlay color, so that the corners of the box stick out past the rounded corners because of this. would like the backgorund overlay to have rounded corners as well.
