Top margin on Nav menu, how to.

[monteiro]

Hi everyone, I'm new to elementor and have been watching lots of videos on how to use it, however, I have come across this template classic.stego-theme.com and want to create a similar, I'm ok with most of it, however, I can't get the top effect of the nav menu, as it looks it's inside another section. I have tried several things but cant do it. I notice also that elementor does now allow you to create a top marging to the nav menu. The same technic is used on all the main sections of the website and i find really cool, maybe someone can point me in the right direction.

many thanks

Jorge
