Hi Veronica
It’s a fair bit of work to include a custom font. You’d need to upload the files to your server via FTP and then we have to use Custom CSS to import them and finally target the correct selectors.
Find a similar font in the Google Fonts library would take a fraction of the time.
If you want to proceed with the custom route, here is a place to start: https://www.fontspring.com/support/installing_webfonts/how-do-i-use-the-webfonts?utm_source=fontsquirrel.com&utm_medium=help_link&utm_campaign=installing_webfonts.
You can upload the font files via FTP to your /wp-content/
folder. All Custom CSS must go in a Custom CSS plugin or at Customize > Additional CSS
.
