## Overview

Comparison dashboard. Ideal for landing pages, modern websites. AI-ready template. Comparison is the oldest analytical act. Before we had dashboards, we had ledgers with columns — last year next to this year, theirs next to ours. Tufte formalized what accountants already knew: small multiples work because they offload memory. You stop asking "what did that other chart look like?" and start seeing differences directly. The eye does the math.

The A/B testing boom of the 2010s turned comparison from an analytical technique into a product category. Optimizely, VWO, Google Optimize — they all needed interfaces that could answer one question fast: which variant won? That pressure produced a specific visual language: paired metrics, confidence intervals rendered inline, green-versus-red delta arrows. The dashboard became a verdict machine.

What's interesting now is how that pattern leaked everywhere. Marketing dashboards compare periods. Competitive intel tools compare brands. The comparative layout isn't a feature anymore — it's an expectation. Users arrive already knowing how to read side-by-side panels because every SaaS product trained them to.

- Density: 8/10 — Dense
- Variance: 4/10 — Moderate
- Motion: 6/10 — Expressive

- **Style:** BI/Analytics
- **Keywords:** Side-by-side comparisons, period-over-period metrics, A/B test results, regional comparisons, performance benchmarks
- **Era:** 2020s Modern
- **Light/Dark:** ✓ Full / ✓ Full

## Colors

- Palette derived from style keywords and era context


## Typography

- **Display / Hero:** System UI stack (-apple-system, sans-serif) — Weight 700, tight tracking, used for headline impact

- **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


## Layout

- **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).


## Elevation & Depth

Comparison bar animations (grow to value), delta indicator animations (direction arrows), highlight on compare

- **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.


## Shapes

Base corner radius: 8px. See rounded tokens in front matter for the full scale.


## Components

- **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.


## Do's and Don'ts

- 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

- Do Period selector works
- Do Deltas calculated
- Do Colors meaningful
- Do Benchmarks shown
- Do Mobile stacks properly
- Do Export comparison


## Use Case

Landing pages, Modern websites

Act as a Senior Frontend Engineer and Expert UI Designer.
Your task is to code a complete Landing Page on the first attempt.
- Landing Page Theme: <INSERT THEME>
- Sections to add: <INSERT SECTIONS>

Generate the final code immediately following these definitions:

## Style

- **Name:** Comparative Analysis Dashboard
- **Type:** BI/Analytics
- **Keywords:** Side-by-side comparisons, period-over-period metrics, A/B test results, regional comparisons, performance benchmarks
- **Era:** 2020s Modern
- **Light/Dark:** ✓ Full / ✓ Full

## Color Palette

- **Primary:** Comparison colors: primary (blue), comparison (orange/purple), delta indicator (green/red)
- **Secondary:** Winning metric color (green), losing metric color (red), neutral comparison (grey), benchmark colors

## Visual Effects

Comparison bar animations (grow to value), delta indicator animations (direction arrows), highlight on compare

## AI Visual Direction

Design a comparison dashboard. Use: side-by-side metrics, period selectors (vs last month), delta indicators (+/-), benchmark lines, A/B comparison tables, winning/losing highlights, percentage change badges.

## CSS Technical

```css
display: flex for side-by-side, gap for comparison spacing, color coding (green up, red down), arrow indicators, diff highlighting, comparison table zebra striping
```

## Design System Variables

```css
--positive-color: #22C55E, --negative-color: #EF4444, --neutral-color: #6B7280, --comparison-gap: 2rem, --arrow-size: 16px, --badge-padding: 4px 8px
```

## Implementation Checklist

- ☐ Period selector works
- ☐ Deltas calculated
- ☐ Colors meaningful
- ☐ Benchmarks shown
- ☐ Mobile stacks properly
- ☐ Export comparison

## 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.
