Meta menu and cursor stuck

Hi, I just discovered Vantage, it’s look great !
I design my home page with a slider and the top of the slider is stuck to the bottom of the menu, no gap.

I have tried the tips you talk about here with no result:

Space below the menu bar and creating a meta slider with responsive buttons

Do I modify the CSS , (not my cup of tea), or is there a normal way to get such a basic layout ?

Thank you for your help
