Okay, I now am using a child theme that someone made
@rod, when you say change Bitter to some other font-family, how do I do this? Or, where do I add the custom CSS to change the font-family?
@combatpost, this means that I just edit the style.css and header.php?
Thank you for your advice but I have already made a significant number of edits to the existing theme. I do not want to lose those changes when changing to a child theme. Isn’t there an easier way (even if it means letting the browser download Bitter pointlessly, just not use it)?
