Is there a way to change the main site font?

Hey @briankelleher ,

Thank you for writing in,

If you do not want to use any plugin or CSS then the only option left is via child theme. You will have to create a child theme for your main theme and customize the code there.

Please go through this article to learn how to create a child theme or download it directly: https://themegrill.com/blog/tutorial-creating-wordpress-child-theme/
