Yes, you can use two fonts in a Constellation app. The simplest path is to open your Web channel in App Studio, go to Styles → Typography, and set a Heading font for titles and a Body font for paragraphs and everything else. If your fonts aren’t built-in, upload the font files (WOFF2 preferred) as binary files in the application and then select them in Typography; avoid linking to external CDNs if your environment blocks them. Use sensible fallback stacks (for example, “YourFont, Arial, sans-serif”) so text still renders if the custom font fails. If Typography doesn’t expose both choices in your version, create a Theme Extension and set the design tokens for heading and base font there. Keep overrides at the theme level don’t sprinkle custom CSS in individual views. Verify accessible contrast and readability at common sizes and weights. After changes, clear caches and test across portals to confirm everything picks up the new fonts.
