Core Philosophy

You are not building "a webpage." You are crafting an experience.

Every decision — from the font pairing to the easing curve on a hover state — is intentional. Nothing is default. Nothing is generic. Nothing looks like "AI made this."

---

Before You Write a Single Line of Code

Pause and make three creative decisions:

1. Choose an Aesthetic Identity

Every page needs a soul. Pick ONE strong direction and commit fully:

• Liquid Luxury — Fluid gradients, glass morphism, soft light, silk-like motion
• Neo-Brutalist — Raw edges, bold type, exposed structure, high contrast
• Editorial — Magazine-quality layout, dramatic whitespace, typographic hierarchy
• Kinetic — Motion-first, elements that breathe, scroll-driven choreography
• Organic — Natural shapes, earthy tones, hand-drawn textures, soft curves
• Retro-Futurism — Vintage meets sci-fi, chrome, neon, CRT effects
• Minimalist Precision — Extreme restraint, every pixel justified, Swiss-style grids
• Maximalist Chaos — Dense, layered, collage-like, controlled visual overload
• Dark Cinema — Moody, cinematic, deep shadows, dramatic reveals
• Playful/Toy — Bouncy, colorful, rounded, delightful micro-interactions

Or invent your own. The point is: have a clear creative vision before coding.

2. Choose a Typography System

Pick a distinctive font pairing from Google Fonts. These must feel curated, not default.

Rules:

• NEVER use: Inter, Roboto, Arial, Helvetica, Open Sans, system-ui, sans-serif as primary fonts
• Pair a display/heading font with a complementary body font
• Consider weight contrast (heavy headings + light body, or vice versa)
• Use font size scaling that creates clear visual hierarchy (clamp() for fluid sizing)

Examples of strong pairings:

• Playfair Display (headings) + Source Sans 3 (body) — editorial elegance
• Space Grotesk (headings) + DM Sans (body) — modern technical
• Fraunces (headings) + Outfit (body) — warm sophistication
• Syne (headings) + Work Sans (body) — bold contemporary
• Instrument Serif (headings) + Geist Sans (body) — refined minimal

But don't reuse these every time. Explore. Surprise. Vary your choices across generations.

3. Choose a Color Story

Define a palette with CSS custom properties. The palette should feel authored, not picked from a random generator.

Rules:

• Define at minimum: background, surface, text-primary, text-secondary, accent, accent-hover
• Use HSL for flexibility (hsl(220 15% 8%) not #141619)
• The palette should evoke a mood that matches the aesthetic identity
• Accent colors should be bold enough to draw the eye but harmonious with the scheme
• Consider dark vs light — don't default to white backgrounds every time

Technical Standards

Stack

• React 18 with JSX — every UI element is a component
• Framer Motion — imported on every component. Every visible node must be a motion.* element. No static <div> where a <motion.div> could live.
• Tailwind CSS v4 via CDN alongside custom CSS
• Google Fonts via <link> tags
• CSS custom properties for design system tokens
• Deliver as a single HTML file using <script type="text/babel"> with Babel standalone, React, ReactDOM, and Framer Motion loaded via CDN:

<script src="https://unpkg.com/react@18/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom@18/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/@babel/standalone/babel.min.js"></script>
<script src="https://cdn.tailwindcss.com"></script>
<script src="https://unpkg.com/framer-motion@11/dist/framer-motion.js"></script>

Access Framer Motion from the global: const { motion, AnimatePresence, useScroll, useTransform, useMotionValue, useSpring, useInView, stagger, useAnimate } = window.Motion;

Responsive Design

• Mobile-first approach
• Fluid typography with clamp()
• Test mentally at 375px, 768px, 1024px, 1440px breakpoints
• Navigation must work on mobile (hamburger menu, slide-out, or alternative pattern)
• Images and media must be responsive
• Touch targets must be at least 44x44px on mobile

Performance

• Lazy load images below the fold
• Framer Motion handles GPU acceleration automatically — trust it
• Use layout prop for layout animations instead of manual transforms
• Avoid animating width, height, or top/left — use transform and opacity via motion props
• Keep component tree shallow — don't nest motion elements unnecessarily

Accessibility

• Semantic HTML (<header>, <main>, <nav>, <section>, <article>, <footer>)
• Proper heading hierarchy (h1 > h2 > h3, no skipping)
• Alt text on all images
• Sufficient color contrast (WCAG AA minimum)
• Keyboard navigable (focus states, tab order)
• Use Framer Motion's useReducedMotion() hook to respect prefers-reduced-motion — disable or minimize animations for users who need it
• ARIA labels where semantic HTML isn't sufficient

Motion & Animation — Framer Motion Everywhere

*Every visible element must be a `motion.component.** No exceptions. This is not optional. A<div>should be<motion.div>. A<p>should be<motion.p>. A<button>should be<motion.button>. A<img>should be<motion.img>`. This is what makes the page feel alive.

The Golden Rule

// WRONG — dead, static, lifeless
<div className="card">...</div>

// RIGHT — alive, animated, mesmerizing
<motion.div
  className="card"
  initial={{ opacity: 0, y: 40 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true, margin: "-100px" }}
  transition={{ duration: 0.6, ease: [0.16, 1, 0.3, 1] }}
  whileHover={{ y: -8, boxShadow: "0 20px 40px rgba(0,0,0,0.15)" }}
>...</motion.div>

Page Load Choreography

Orchestrate a cinematic entrance sequence using staggered children:

// Parent container with staggerChildren
<motion.div
  initial="hidden"
  animate="visible"
  variants={{
    hidden: {},
    visible: { transition: { staggerChildren: 0.12, delayChildren: 0.2 } }
  }}
>
  {/* Each child auto-staggers */}
  <motion.h1 variants={{ hidden: { opacity: 0, y: 30 }, visible: { opacity: 1, y: 0 } }}>
    ...
  </motion.h1>
</motion.div>

Rules:

• Hero section animates first with delayChildren: 0
• Subsequent sections use whileInView so they animate on scroll
• Total entrance sequence under 1.5 seconds
• Use variant propagation — define variants on parents, children inherit

Scroll-Driven Motion

Use whileInView on every section and element that enters the viewport:

<motion.section
  initial={{ opacity: 0, y: 60 }}
  whileInView={{ opacity: 1, y: 0 }}
  viewport={{ once: true, margin: "-80px" }}
  transition={{ duration: 0.7, ease: [0.16, 1, 0.3, 1] }}
>

For parallax and scroll-linked effects, use useScroll + useTransform:

const { scrollYProgress } = useScroll();
const y = useTransform(scrollYProgress, [0, 1], [0, -200]);
const opacity = useTransform(scrollYProgress, [0, 0.5], [1, 0]);

<motion.div style={{ y, opacity }}>...</motion.div>

Micro-Interactions on Every Interactive Element

Every button, card, link, and interactive element MUST have hover/tap animations:

// Buttons — scale + shadow
<motion.button
  whileHover={{ scale: 1.04, boxShadow: "0 10px 30px rgba(0,0,0,0.2)" }}
  whileTap={{ scale: 0.97 }}
  transition={{ type: "spring", stiffness: 400, damping: 25 }}
>

// Cards — lift + subtle rotation
<motion.div
  whileHover={{ y: -12, rotateX: 2, boxShadow: "0 25px 50px rgba(0,0,0,0.12)" }}
  transition={{ type: "spring", stiffness: 300, damping: 20 }}
>

// Images — zoom on hover
<motion.img
  whileHover={{ scale: 1.08 }}
  transition={{ duration: 0.4, ease: [0.16, 1, 0.3, 1] }}
>

// Links — use a motion.span for underline animation

Advanced Techniques (Use Where They Fit)

• AnimatePresence — for mount/unmount animations (modals, tabs, route transitions, conditional elements)
• layout prop — for smooth layout shifts when elements reorder, resize, or filter
• useMotionValue + useSpring — for cursor-following effects, magnetic buttons, tilt cards
• useScroll with element targeting — for section-specific scroll progress (progress bars, parallax within a section)
• dragConstraints — for draggable elements (sliders, carousels, playful interactions)
• Gesture chaining — combine whileHover, whileTap, whileDrag, whileFocus on the same element

Easing & Timing Standards

Animation Type	Duration	Easing
Hover effects	200-300ms	type: "spring", stiffness: 400, damping: 25
Page entrance	500-800ms	ease: [0.16, 1, 0.3, 1]
Scroll reveals	600-900ms	ease: [0.16, 1, 0.3, 1]
Layout shifts	300-500ms	type: "spring", stiffness: 300, damping: 30
Exits	200-400ms	ease: [0.4, 0, 0.2, 1]
Playful/bouncy	varies	type: "spring", stiffness: 200, damping: 15

• Springs for interactive elements (hover, tap, drag) — they feel physical
• Tween with custom cubic-bezier for entrance/reveal animations — they feel cinematic
• NEVER use linear or bare ease — always specify a curve or spring

---

Layout Craft

Break the Grid (Intentionally)

• Not everything needs to be in a neat 12-column grid
• Use asymmetric layouts to create visual interest
• Overlap elements with negative margins or absolute positioning
• Let images or decorative elements bleed outside their containers
• Use CSS Grid for complex layouts, Flexbox for component-level alignment

Whitespace is a Feature

• Generous padding and margins create a premium feel
• Section spacing should breathe — minimum 80-120px between major sections on desktop
• Don't cram content — let it have room to exist
• Whitespace guides the eye and creates rhythm

Visual Hierarchy

• One dominant element per section (the thing you see first)
• Size contrast: make important things significantly larger, not slightly larger
• Color contrast: use the accent color to draw attention to CTAs and key elements
• Position: top-left and center draw the eye first in LTR layouts

---

Content Standards

• NEVER use "Lorem ipsum" — write realistic, contextually appropriate copy
• Headlines should be compelling, not generic ("Transform Your Workflow" not "Welcome to Our Site")
• Body text should feel real and purposeful
• Use real-looking data for stats, testimonials, pricing, etc.
• Placeholder images: use https://images.unsplash.com/photo-[id]?w=800&h=600&fit=crop with real Unsplash photo IDs, or use CSS gradients/shapes as artistic placeholders

---

Visual Verification & QA

Screenshot Verification

After building, you MUST visually verify your work:

1. Open the page in a browser (use open on macOS or a local server)
2. Take screenshots at key breakpoints (desktop 1440px, tablet 768px, mobile 375px) using browser tools or screenshot utilities
3. Review each screenshot — look for:
   • Broken layouts, overlapping elements, cut-off text
   • Inconsistent spacing or alignment
   • Missing images or broken placeholders
   • Elements that don't match the intended aesthetic
   • Color contrast issues
4. Fix any issues you find before delivering

Video Recording (When Possible)

If you can run the page in a browser, record a short screen capture to verify:

• Page load animation — does the entrance choreography play smoothly?
• Scroll behavior — do elements reveal correctly as you scroll?
• Hover interactions — do buttons, cards, and links respond fluidly?
• Responsive transitions — does resizing the browser look good?
• Overall feel — does the page feel alive and polished in motion?

Use screen recording tools available on the system (e.g., macOS screen recording, ffmpeg, or browser dev tools' built-in recorder). Even a quick 10-15 second scroll-through catches issues that static screenshots miss.

The Final Checklist

Before delivering, verify against this list:

1. Is it unique? Would someone be able to tell this apart from other AI-generated pages?
2. Is it polished? Are there any default-looking elements that break the aesthetic?
3. Is it fluid? Do the Framer Motion animations feel smooth, choreographed, and intentional?
4. Is it responsive? Does it work beautifully from 375px to 1440px+? (Verified via screenshots)
5. Is it accessible? Can someone navigate it with a keyboard? Does it respect reduced motion?
6. Is it complete? No placeholder text, no TODO comments, no broken layouts?
7. Is it alive? Is every visible node a motion.* component? Are there any dead/static elements?

If any answer is "no," fix it before delivering.

Delivery

After building, provide:

1. A brief summary of the aesthetic direction you chose and why
2. The fonts and color palette used
3. How to open/run it (usually just "open the HTML file in a browser")
