Design System: Brutalism

1. Visual Theme & Atmosphere

Brutalist landing page with raw, stark, intentionally unpolished aesthetics. Ideal for streetwear, marcas experimentais, layouts editoriais, portfólios de design. AI-ready template.

• Density: 5/10 — Balanced
• Variance: 2/10 — Structured
• Motion: 4/10 — Subtle

2. Color Palette & Roles

• Pure Black (#000000) — Dark surface, primary background
• Pure White (#FFFFFF) — Light surface, card backgrounds
• Neon Green (#00FF00) — Supporting palette color
• Hot Pink (#FF00FF) — Primary text color
• Electric Blue (#0000FF) — Secondary accent
• Bright Red (#FF0000) — Error states, destructive actions
• Yellow (#FFFF00) — Warning states, attention indicators
• Grey (#808080) — Secondary text, borders, muted elements

3. Typography Rules

• Display / Hero: Courier New — Weight 700, tight tracking, used for headline impact
• Body: Courier New — Weight 400, 16px/1.6 line-height, max 72ch per line
• UI Labels / Captions: Courier New — 0.875rem, weight 500, slight letter-spacing
• Monospace: Courier New — Used for code, metadata, and technical values

Scale:

• Hero: clamp(2.5rem, 5vw, 4rem)
• H1: 2.25rem
• H2: 1.5rem
• Body: 1rem / 1.6
• Small: 0.875rem

4. Component Stylings

• Primary Button: Sharp edges (0px) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows.
• Secondary / Ghost Button: Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill.
• Cards: Sharp edges (0px) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke.
• Inputs: Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels.
• Navigation: Primary surface background. Active item: accent color indicator. Font weight 500 when active.
• Skeletons: Shimmer animation matching component dimensions. No circular spinners.
• Empty States: Icon-based composition with descriptive text and action button.

5. Layout Principles

• Grid: CSS Grid primary. Max-width containment: 1280px centered with 1.5rem side padding.
• Spacing rhythm: Balanced. Base unit: 0.5rem (8px).
• Section vertical gaps: clamp(4rem, 8vw, 8rem).
• Hero layout: Split-screen (text left, visual right).
• Feature sections: Zig-zag alternating text+image rows. No 3-equal-columns.
• Mobile collapse: All multi-column layouts collapse below 768px. No horizontal overflow.
• z-index contract: base (0) / sticky-nav (100) / overlay (200) / modal (300) / toast (500).

6. Motion & Interaction

• Physics: Ease-out curves, 200-300ms duration. Smooth and predictable.
• Entry animations: Fade + translate-Y (16px → 0) over 420ms ease-out. Staggered cascades for lists: 80ms between items.
• Hover states: Subtle color shift + shadow adjustment over 200ms.
• Page transitions: Fade only (200ms).
• Performance: Only transform and opacity animated. No layout-triggering properties.

7. Anti-Patterns (Banned)

• No emojis in UI — use icon system only (Lucide, Heroicons)
• No pure black (#000000) — use off-black or charcoal variants
• No oversaturated accent colors (saturation cap: 80%)
• No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
• No h-screen — use min-h-[100dvh]
• No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
• No broken external image links — use picsum.photos or inline SVG
• No generic lorem ipsum in demos

AI Visual Direction

Design a brutalist landing page with raw, stark, intentionally unpolished aesthetics. Use pure black, white with neon accent colors. No smooth transitions (instant), sharp corners (0px), bold oversized typography (weight 900), visible thick borders, monospace or system fonts. Intentionally 'broken' overlapping layouts. Anti-design that challenges conventional polish. Raw, loud and unapologetic.

CSS Technical

font-family: 'Courier New', monospace or system-ui, font-weight: 900, font-size: clamp(2rem, 8vw, 10rem), background: #FFFFFF or #000000, color: #000000 or #FFFFFF, border: 4px solid #000000, border-radius: 0px, transition: none, text-transform: uppercase, mix-blend-mode: difference on overlapping elements

Design System Variables

--color-black: #000000, --color-white: #FFFFFF, --color-accent1: #00FF00, --color-accent2: #FF00FF, --font-primary: monospace, --font-weight: 900, --border: 4px solid #000000, --border-radius: 0px, --transition: none, --spacing: 1rem

Implementation Checklist

• ☐ No border-radius (0px everywhere)
• ☐ No smooth transitions
• ☐ Bold oversized typography (900)
• ☐ Visible thick borders
• ☐ Monospace or system fonts
• ☐ Intentionally raw/broken layout
• ☐ High contrast B&W + neon accents
• ☐ Responsive with maintained rawness

Execution Rules

1. Strictly follow the defined visual style.
2. Use high-quality inline SVG icons (Heroicons or Lucide style) — NEVER use emojis as icons.
3. Add cursor-pointer and smooth hover states (transition-all) on all interactive elements.
4. Required Page Structure:
   • Navbar (Logo + Links + CTA)
   • Hero Section (Impactful Headline + Subtitle + 2 buttons + 3D/Abstract visual element via CSS)
   • Features (3 cards with icons)
   • Testimonials (3 cards)
   • Pricing (3 tiers, highlight the middle one)
   • Final CTA
   • Full Footer with social links, privacy policy, terms of use, contact and SEO links.
5. All text content must be in English.
6. The visual must be CLEARLY distinct — do not create a "default Bootstrap" design. Force the use of the provided design system variables.
7. Use <style> tags in the head for custom classes (especially for complex backdrop-filter effects and animations) that Tailwind CDN doesn't cover.
8. Full Responsiveness: Layout must adapt perfectly to Mobile, Tablet and Desktop (vertical stack on mobile).
9. Include basic SEO, Viewport and Open Graph meta tags in <head>.
10. Footer must contain: Copyright 2026, Secondary navigation links and Social media icons.
11. Make the creative decisions needed to deliver the complete, functional result now.
