Theme Sizer: Forms & Sections
The Opportunity
A no-code visual control panel to adjust widths, paddings, and layout of contact forms and common sections across themes. Works via an app block and CSS variables—no manual code edits needed.
"Non-technical merchants frequently want simple presentation fixes like making contact forms wider but lack CSS skills and risk breaking theme code."
Market Validation
Detailed Analysis
Proposed Solution
Provide sliders and presets to set max-width, spacing, and alignment for forms and key sections; inject safe, theme-scoped CSS via a theme app extension with instant preview and 1-click revert.
Target Audience
Merchants and theme customizers who need quick styling fixes without editing code; agencies seeking faster repetitive tweaks.
Competitive Landscape
Hulk Form Builder, POWR Form Builder, qikify Contact Form Builder, Custom CSS helper plugins
Implementation Notes
Create a theme app extension that mounts app blocks and injects a small stylesheet with CSS variables. Detect common OS 2.0 section/form selectors (e.g., Dawn family) and allow per-template overrides. Build a live preview with postMessage to update variables in real time. Provide presets (narrow/standard/wide/full) and granular sliders for max-width/margins/padding. Store settings in app metafields per theme. Offer a safe uninstall cleanup routine.
