Changing the Menu Font and Size

Hello! I was wondering if it is possible to change the actual menu font itself, and also the font size?
I have tried a few of the suggestions on this forum, but they didn’t work. Thank you so much for your time!

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.
Simply adjust the font size and font family to that of your liking.

Admin Area -> Appearance -> Customize -> Additional CSS

/change men font and size/ a {
font-family: roboto;

Font Family:

Best Regards,

Hi there thank you for your reply. Ok so I tried this with different font families and also with different font sizes, but the menu always stayed the same.
I am running Word Press 4.8.1.
Is there something I am doing wrong?
