Hello!

I'd like to add sponsor logos in the header part of the Skylar template with a different color (dark blue) than the showcase and top modules (white). However, the logos don't fit in that dark part so I would need to make the depth slightly bigger. I guess that it is done in the Custom CSS tab of the template but I don't know what to add.
Could you help me with the code I need to add?
Thanks.
