Hello Ciaran,
I walked into a strange issue/bug.
I have a ImageHover module in base-1a of the Nina template.
The same module with the same content I use in 2 versions:
1. In carousel layout with the 'hidden-tablet hidden-desktop' module class.
2. As static layout with the 'hidden-phone' module class.
On desktop, when I have them both published, the padding on top in base1 disappears.
See the diference between the screenshots.
Any idea?
