Topic summary
Goal: Use two different fonts within a single banner heading in Shopify’s Dawn 15.0, with custom Good Sans and Flecha L Italic fonts uploaded as .woff assets.
Issue: The Flecha font wasn’t applying and appeared to fall back to Times New Roman.
Implementation: Style the target words via the rich text editor (italic/em) in the Image Banner heading, then add a CSS rule in section-image-banner.css targeting h2.banner__heading em to set font-family (and optional font-style). The em tag denotes emphasized (typically italic) text.
Font loading: Ensure the font files in the assets folder are correctly referenced in theme.liquid (the main theme layout file), e.g., via @font-face, and that file and font-family names match exactly.
Resolution: The font began working after correcting a name mismatch—changing “Flecha L” to “FlechaL” to align with the uploaded asset filename, resolving the CSS reference.
Outcome: Multiple fonts in one heading achieved; guidance and code approach provided; no remaining questions. Discussion resolved.
