Fonts
Customize typography on your documentation site with Google Fonts or self-hosted font files for headings, body text, and code blocks.
Set a custom font for your entire site or separately for headings and body text. Use Google Fonts, local font files, or externally hosted fonts. The default font varies by theme.
Configure fonts with the fonts property in your docs.json.
