Frontend Design Skill
Design and implement memorable frontend interfaces with a clear, intentional aesthetic. The output must be real, working code — not just mood boards. This skill is about design thinking + execution : every visual choice should be rooted in purpose and context.
When to Use
Use this skill when the user wants to:
- Create a new web page, landing page, dashboard, or app UI
- Design or redesign frontend components or screens
- Improve typography, layout, color, motion, or overall visual polish
- Convert a concept or brief into a high‑fidelity, coded interface
Inputs to Gather (or Assume)
Before coding, identify:
- Purpose & audience: What problem does this UI solve? Who uses it?
- Brand/voice : Any reference brands, tone, or visual inspiration?
- Technical constraints : Framework, library, CSS strategy, accessibility, performance
- Content constraints : Required copy, assets, data, features
If the user did not provide this, ask 2–4 targeted questions , or state reasonable assumptions in a short preface.
Design Thinking (Required)
Commit to a single, bold aesthetic direction. Name it and execute it consistently. Examples:
- Brutalist / raw / utilitarian
- Editorial / magazine / typographic
- Luxury / refined / minimal
- Retro‑futuristic / cyber / neon
- Art‑deco / geometric / ornamental
- Handcrafted / organic / textured
Avoid generic AI aesthetics. No “default” fonts, color schemes, or stock layouts.
Before writing code, define the system:
- Visual direction — one sentence that describes the vibe
- Differentiator — what should be memorable about this UI?
- Typography system — display + body fonts, scale, weight, casing
- Color system — dominant, accent, neutral; define as CSS variables
- Layout strategy — grid rhythm, spacing scale, hierarchy plan
- Motion strategy — 1–2 meaningful interaction moments
If the user wants code only, skip the explanation but still follow this internally.
Implementation Principles
- Working code : HTML/CSS/JS or framework code that runs as‑is
- Semantic & accessible: headings, labels, focus states, keyboard nav
- Responsive : fluid layouts, breakpoints, responsive typography
- Tokenized styling : CSS variables for colors, spacing, radii, shadows
- Modern layout : prefer CSS Grid/Flex, avoid brittle positioning hacks
Aesthetic Guidelines
Typography
- Typography should define the voice of the design
- Avoid default fonts (Inter, Roboto, Arial, system stacks)
- Use a distinct display font + a refined body font
- Implement a clear hierarchy (size, weight, spacing, casing)
Color & Theme
- Commit to a palette with a strong point‑of‑view
- Avoid timid, overused gradients (e.g., purple‑to‑pink on white)
- Use contrast intentionally and check legibility
Composition & Layout
- Encourage asymmetry, scale contrast, overlap, or grid breaks
- Use negative space deliberately (or controlled density if maximalist)
- Create visual rhythm and hierarchy through spacing and alignment
Detail & Atmosphere
- Add texture or depth when appropriate (noise, grain, subtle patterns)
- Use shadows/glows only when they serve the concept
- Consider unique borders, masks, or clip‑paths for distinct shapes
Motion & Interaction
- Use motion sparingly but meaningfully
- Favor one standout interaction over many tiny ones
- Honor
prefers-reduced-motion
Avoid
- Cookie‑cutter hero + 3 card layouts
- Generic gradients and default font choices
- Unmotivated decorative elements
- Overly flat, characterless component libraries
Deliverables
- Provide full code with file names or component boundaries
- Make customization easy with CSS variables or config objects
- If assets are needed, provide inline SVGs or generative CSS patterns
Quality Checklist (Self‑validate)
- Aesthetic direction is unmistakable
- Typography feels intentional and expressive
- Layout and spacing are consistent and purposeful
- Color palette feels cohesive and legible
- Interactions enhance the experience without clutter
- Code runs as provided and is production‑ready
Remember: a design is only as strong as its commitment. Choose a direction and execute it relentlessly.
