Hey @overlagsen,
I’m not sure what you mean by “it moves and is no longer centrered”. Would you mind recording a screencast?
Centering an element perfectly is certainly achievable using custom CSS but regretfully, we would be veering into custom development because you’ll need more code if we go with that method and that is outside the scope of our support.
Please follow the setup in this screencast instead. Gap elements should also work and the added benefit of using gaps is you can hide it based on screen size because it has Hide During Breakpoints option.
Hope that helps and thank you for understanding.
