Twenty Sixteen – remove space between logo and nav

Hi. I saw that this has been asked a few times, and two of the questions were marked as resolved but the solutions in those threads did not change anything for me.

I’m trying to make their be less space between the logo and the nav menu.

Does anyone know what code to put in the CSS? I’ve tried changing the padding and margins in tons of different possible places in the CSS and nothing has any visual effect at all. Thank you.
