What problem does it solve?
It fixes poor mobile funnel experiences caused by missing viewport setup, desktop-first layouts, undersized touch targets, and non-thumb-friendly CTAs that hurt conversions.
Core Features & Use Cases
- Mobile-first layout checklist: Ensures single-column stacking on small screens and grid behavior only after 768px.
- Sticky CTA bar pattern: Adds a fixed bottom CTA on pages longer than one viewport so the primary action never scrolls away.
- Mobile usability guardrails: Enforces 44px+ (CTA/button/link/input) touch targets, 16px minimum body/type sizing to prevent iOS focus zoom, and form rules that prevent side-by-side fields on mobile.
- Breakpoint and type scale standards: Provides a consistent mobile base plus tablet/desktop scale steps and a max-width container cap.
- Required meta and testing protocol: Requires viewport meta, prevents horizontal scroll at 375px, and specifies a testing matrix for real-device portrait and landscape.
Quick Start
Apply the mobile-responsive checklist to your funnel page build and adjust breakpoints, touch targets, and the sticky bottom CTA until it passes the 375, 414, 768, 1024, and 1280 mobile testing checks.
