Font Coding

Site URL: http://reidbrenner.com

I have been trying to change the font of the title of my website and I havent seemed to be able to do it.  I purchased a webfont and the font itself and would love if someone would help me code it to change the website font and my website title font.

Whats the password and which font?

Do you have a URL or a font file?

If you use SS 7.1. Upload font file to your site then Add to Home > Design > custom CSS

@font-face { 
  font-family: nexa; 
  src: url(https://static1.squarespace.com/static/5d2b34d977f80900014edb0d/t/5e3f7cb899dd6e23d8b1e836/1581219002767/nexa-regular.otf); 
} 
a#site-title {
    font-family: nexa;
}
