How to remove extra space

Hi,

I am using your READ theme and on this website: https://attention.cc/ I cannot figure out how to remove the extra space between the 6 red buttons on the top and header. I used the same theme on this website: https://mtsblog.rs/ many months ago and I was able to remove it succesfully, but now I can't figure it out. I am basically building replica of https://mtsblog.rs/ and would like attention.cc to look exactly the same as https://mtsblog.rs/.

How do I push these 6 red buttons on the top more toward the top?
