Responsive Web Layout System Designer

What You Can Do
You can systematically design reusable responsive grid systems, establish spacing scales and breakpoint strategies, and document component layout behaviors for seamless developer handoff. This skill generates technical layout specifications that reduce design-to-development friction and ensure accessibility compliance from the design phase, enabling teams to build consistent, scalable web interfaces across all devices.
Features
Create 12-column, CSS Grid, or custom grid specifications with mobile-first breakpoints (320px, 768px, 1024px, 1440px+)
Define and document min-width, max-width, and fluid scaling rules for components across devices
Generate modular spacing scales (4px, 8px, 16px, 24px base) with consistent padding/margin rules for component libraries
Embed color contrast ratios, touch target minimums (48px), and semantic HTML guidance into layout specs
Specify how components stack, wrap, hide, or resize at each breakpoint with technical details for developers
Produce reusable frameworks for buttons, cards, forms, navigation, and data tables with responsive rules
Export markdown or HTML specs with code examples, CSS class naming conventions, and implementation guidance
Example Output
Example 1: Grid System Specification
- 12-column mobile grid (320px): Full width, 16px gutters
- Tablet grid (768px): 8-column, 24px gutters, max-width 100vw
- Desktop grid (1024px): 12-column, 32px gutters, max-width 1200px
- CSS Grid template areas documented with fallback float layouts
Example 2: Component Spacing Scale
- xs: 4px (micro spacing for inline elements)
- sm: 8px (button padding, small gaps)
- md: 16px (card padding, section spacing)
- lg: 24px (component margins, container padding)
- xl: 32px (section breaks, major spacing)
Example 3: Form Component Responsive Spec
- Mobile (320px): Single-column layout, full-width inputs, 44px min touch height
- Tablet (768px): Two-column layout, inputs 48px tall, labels above fields
- Desktop (1024px): Three-column layout, inputs 40px tall, side-by-side labels, ARIA-labels documented for screen readers
What's Included
- SKILL.md: Core instruction file for generating layout systems
