Responsive Craft

Implement responsive design that works across all viewports — compensating for the lack of a visual canvas by making deliberate decisions upfront.

Quick Start

Transform an existing site: /responsive-craft audit or "make this responsive" or "fix the mobile layout" Build responsive from scratch: /responsive-craft build or "build this mobile-first" or "create a responsive layout" Preview all breakpoints: /responsive-craft preview or "show me the responsive preview" or "open the breakpoint preview"

Core Principles

Escalation model — Intrinsic CSS first (auto-fit, flex-wrap, clamp()) → container queries next (component-level) → media queries last (page-level only). If a simpler layer solves it, stop there.
Describe before you code — Without a canvas, explicitly describe responsive behavior before writing CSS. In Adaptive mode, use inline behavior notes (CSS comments). In Guided mode, write formal behavior specs (tables per component). Both catch design decisions a canvas would reveal passively.
Fluid by default, breakpoints by exception — Use clamp() for typography, spacing, sizing. Reserve hard breakpoints for structural changes: nav transforms, column count shifts, sidebar visibility.
