Frontend Design

Overview

Create distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

Output Requirements

MANDATORY: The entry HTML file MUST be named index.html.

Design Thinking

Before coding, understand the context and commit to a BOLD aesthetic direction:

• Purpose: What problem does this interface solve? Who uses it?
• Tone: Pick an extreme: brutally minimal, maximalist chaos,

retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc.

• Constraints: Technical requirements (framework, performance, accessibility)
• Differentiation: What makes this UNFORGETTABLE? What's the one thing

someone will remember?

CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work — the key is intentionality.

Then implement working code (HTML/CSS/JS, React, Vue, etc.) that is:

• Production-grade and functional
• Visually striking and memorable
• Cohesive with a clear aesthetic point-of-view
• Meticulously refined in every detail

Frontend Aesthetics Guidelines

Typography

• Choose fonts that are beautiful, unique, and interesting
• Avoid generic fonts (Arial, Inter, Roboto, system fonts)
• Pair a distinctive display font with a refined body font
• Use Google Fonts or local font files

Color & Theme

• Commit to a cohesive aesthetic
• Use CSS variables for consistency
• Dominant colors with sharp accents outperform timid, evenly-distributed palettes
• Avoid cliched purple gradients on white backgrounds

Motion

• Use animations for effects and micro-interactions
• Prioritize CSS-only solutions for HTML
• Focus on high-impact moments: one well-orchestrated page load with staggered

reveals creates more delight than scattered micro-interactions

• Use scroll-triggering and hover states that surprise

Spatial Composition

• Unexpected layouts. Asymmetry. Overlap. Diagonal flow
• Grid-breaking elements
• Generous negative space OR controlled density

Backgrounds & Visual Details

• Create atmosphere and depth rather than defaulting to solid colors
• Add contextual effects and textures: gradient meshes, noise textures,

geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, grain overlays

NEVER use generic AI-generated aesthetics:

• Overused font families (Inter, Roboto, Arial)
• Cliched color schemes (purple gradients on white)
• Predictable layouts and component patterns
• Cookie-cutter design that lacks context-specific character

Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code. Minimalist designs need restraint, precision, and careful attention to spacing, typography, and subtle details.

Workflow

1. Understand the user's frontend requirements
2. Choose an aesthetic direction (tone, fonts, colors, motion)
3. Generate the HTML/CSS/JS code:

write_file("index.html", "<full HTML content>") write_file("styles.css", "<full CSS content>") write_file("script.js", "<full JS content>")

1. Present the file path so the user can open it in a browser

Pitfalls

• Generic aesthetics: the #1 failure mode. If it looks like every other

AI-generated page, redo it with a bolder direction.

• Font convergence: don't use the same fonts across every project. Vary.
• Over-animation: too many animations overwhelm. One well-orchestrated

moment beats ten scattered micro-interactions.

• No dark mode: consider whether the design should support dark mode.
• Accessibility: bold aesthetics must not sacrifice readability. Check

contrast ratios, font sizes, focus states.
