Custom fonts

@sg23838586 Not without creating a child theme with a different set of fontfamilies added in the theme.json, as far as I know. At least not if you want the font families to work correctly in the Global Styles section of the Site Editor.

@sg23838586 No worries! If you add the contents of the code block below to the theme.json file in your child theme, you should be good to go:

}

Note that this code replaces all of the font families included in Beaumont itself, so the theme will look a bit busted at first. When you’ve added the code and activated the theme:

1. Go to Appearance → Editor
2. Click the Global Styles icon in the top right
3. Click Typography → Text in the panel, and
4. Change the “Font” setting from “Default” to “Source Serif Pro”.

Let me know how it goes!

I did write pretty much all of the the theme.json file myself, but when you’ve released themes with 4000+ lines of CSS, 700+ lines of JSON doesn’t seem so bad 😃
