Change CSS of header theme

[doldy101]

Hi,

I have added wordpress to my site to be used as a blog. I edited the standard twentyseventeen theme to match the rest of my web pages, which I have done, except for the font on the nav bar.

I downloaded the theme, updated it and its still not updating.

I have included screenshots of the way my nav bar is formatted on the other pages to the way its formatted on my wordpress site. 

How can I get the nav bar on the wordpress site to match the nav bar on my other pages?
