For the rare thing the theme settings don’t cover, use Settings → Theme → Custom CSS & Fonts. This is the highest-priority layer, so use it sparingly and deliberately.
Custom fonts
- Google Fonts URL — paste a Google Fonts stylesheet link to load extra families (they’ll then appear in the Typography pickers).
- Uploaded fonts — brand fonts you upload become available as font choices too.
Custom CSS
A free-form CSS box, applied last — after every theme setting — so it can adjust anything. Use it for fine details the panels don’t expose.
⚠️ Warning: Custom CSS overrides your theme, so it can also break dark mode or responsiveness if it hardcodes values. Prefer the theme settings first; reach here only when you must, and test both light and dark mode after.
💡 Tip: Scope custom rules tightly (target a specific block’s id or class) so a broad rule doesn’t have side effects elsewhere on the site.
Next: Per-block overrides.
