The Opportunity

A lightweight theme app extension that adds true inline color and typography controls to any Rich Text block without needing a full page builder. Editors can highlight words or phrases and apply colors from the store’s palette with built‑in accessibility checks.

"Merchants cannot easily change the color of specific words or phrases inside a single rich text section, a task that is trivial on many other platforms."

Detailed Analysis

Proposed Solution

Provide a custom WYSIWYG editor app block for Online Store 2.0 that outputs sanitized HTML spans mapped to theme color variables, enabling per‑word color, highlights, and emphasis with palette and contrast guidance.

Target Audience

Merchants and content editors who need granular text styling without adopting a full page builder

Competitive Landscape

PageFly, Shogun, GemPages, Blog Studio by ShopPad, Zeno Page Builder, Design Packs (sections library)

Implementation Notes

Build a Theme App Extension with an App Block exposing a custom editor (Tiptap/ProseMirror or TinyMCE) embedded via App Bridge and Polaris. Store editor output as sanitized HTML or JSON in block settings or a metaobject; render via block.liquid. Map color options to theme settings using CSS variables to keep branding consistent. Include an inline WCAG contrast checker and restrict choices to the theme palette (with optional custom colors). Provide responsive typography controls, undo/redo, and safe paste cleanup. No reliance on modifying Shopify’s native RTE; all styling occurs within the app block for predictable output.
