Design System: Underwater / Aquático

1. Visual Theme & Atmosphere

Design an underwater aquatic infographic. Ideal for landing pages, modern websites. AI-ready template. Underwater / Aquático style represents a modern trend in UI/UX web design focused on infographic.

• Density: 5/10 — Balanced
• Variance: 4/10 — Moderate
• Motion: 6/10 — Expressive

2. Color Palette & Roles

• Light Aqua (#E0F6FF) — Primary surface or dominant color
• Deep Navy (#0B3C5D) — Secondary surface or text color
• Ocean Blue (#006994) — Accent highlight, links and focus states
• Cerulean (#0277BD) — Supporting palette color
• Dark Blue (#01579B) — Deep contrast surface
• Teal (#004D73) — Secondary accent
• Steel Blue (#005885) — Secondary accent
• Cobalt (#0D47A1) — Extended palette, decorative use

3. Typography Rules

• Display / Hero: System UI stack (-apple-system, sans-serif) — Weight 700, tight tracking, used for headline impact
• Body: System UI stack (-apple-system, sans-serif) — Weight 400, 16px/1.6 line-height, max 72ch per line
• UI Labels / Captions: System UI stack (-apple-system, sans-serif) — 0.875rem, weight 500, slight letter-spacing
• Monospace: JetBrains Mono — 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: Subtly rounded (0.5rem) 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: Subtly rounded (0.5rem) 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: Spring — stiffness 120, damping 20. Confident, weighted transitions.
• Entry animations: Fade + translate-Y (16px → 0) over 480ms ease-out. Staggered cascades for lists: 100ms between items.
• Hover states: Scale(1.03) + shadow lift over 200ms.
• Page transitions: Fade + slide (300ms).
• 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

• Era: Nature Aquatic
• Light/Dark: ✓ Full / ✓ Full

Color Palette

• Primary: Light Aqua #E0F6FF, Deep Navy #0B3C5D, Ocean Blue #006994, Cerulean #0277BD
• Secondary: Dark Blue #01579B, Teal #004D73, Steel Blue #005885, Cobalt #0D47A1, flowing liquid

Visual Effects

Cool blue illumination, underwater lighting effects, bubble floating animations, wave motion, fish swimming paths, coral sway, depth layering

AI Visual Direction

Design an underwater aquatic infographic. Use: underwater elements (fish, coral, plants, bubbles), ocean blue palette, wave patterns, layered depth suggesting ocean environment, cool blue illumination, flowing liquid aesthetic, marine life decorations.

CSS Technical

background: linear-gradient(180deg, #E0F6FF, #006994), SVG marine elements, animation: bubble-rise (translateY), wave SVG (sine curve), layered z-index for depth, filter: blur for distance, cool blue palette

Design System Variables

--light-aqua: #E0F6FF, --deep-navy: #0B3C5D, --ocean-blue: #006994, --bubble-size: 8px, --bubble-duration: 4s, --wave-amplitude: 20px

Implementation Checklist

• ☐ Ocean blue palette
• ☐ Marine elements present
• ☐ Bubble animations
• ☐ Wave patterns
• ☐ Depth layering
• ☐ Calming underwater feel

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.
