Changing site font issue

Hey,

I was trying to change site font and added this to the additional css:

    .main-navigation a { 
      font-family: 'open sans hebrew', cursive;
    }

it changed the menu font but when I click on other pages the menu font did not change, only at the front page.

how can I change it on the rest of the page, or just force the website to have everything with a specific font?

Thank you!

Hello,

Can you please provide a link to your website?

Kind Regards, Roman.
