Reverse-Engineered Prompt

> Re-create the Voltmaster Pro – Advanced Electrical Solutions single-page template from scratch using only HTML5, CSS3 and vanilla ES6 JavaScript.

The final artifact must be a pixel-perfect, fully-responsive, production-ready landing page that looks & behaves exactly like the reference URL.

---

3. Section-by-Section Specs

Hero
- Full-height viewport (100 vh)
- Animated headline fade-in-up 0.8 s ease-out
- CTA button with electric-blue → cyan gradient on hover & 4 px lift
- Background: subtle circuit-board SVG pattern (base64 encoded)

Services
- 3 service cards: EV Charging | Smart Homes | Panel Upgrades
- Each card: icon, title, 1-line description, “Learn more” link
- Hover: scale 1.03, shadow deepen, icon rotate 8°

Process
- 4-step horizontal timeline on desktop, vertical on ≤ 768 px
- Step circles numbered 01-04, connected by animated progress line that fills on scroll into view (IntersectionObserver)

Our Work
- Static image of smart-home diagram with 5 interactive hotspots
- Hovering a hotspot reveals a tooltip with technology name & 15-word blurb
- Tooltip positioning flips to stay inside viewport

Client Feedback
- Auto-looping carousel, 5 s interval, pause on hover
- Dots indicator, keyboard arrows support, touch swipe on mobile
- Each slide: photo, name, star rating (inline SVG), 25-word testimonial

Technology Stack
- 4-column grid on desktop, 2 on tablet, 1 on mobile
- Each tile: icon, title, micro-copy (≤ 12 words)
- Subtle pulse animation on icon every 4 s (respects prefers-reduced-motion)

Clients
- Marquee-style logo strip: NEXUS CORP | APEX | STELLAR | ORION | NOVA
- Logos are monochrome SVG, 120 px wide, 40 px tall
- Infinite scroll left → right, pause on hover

Contact
- Sticky “Get a Quote” button in bottom-right (z-index 100)
- Modal form: name, email, phone, service select, message
- Client-side validation + HTML5 required attributes
- On submit: async POST to `/api/contact` (mock with `setTimeout`), show success toast

Footer
- © 2025 Voltmaster Pro – All rights reserved
- Social icons: Twitter, LinkedIn, Instagram (SVG, 32 px)
- Back-to-top button appears after 600 px scroll

---

4. Micro-interactions & Behavior
- Smooth-scroll for all same-page anchor links (scroll-behavior polyfill for Safari)
- Navigation bar becomes sticky with background blur after 80 px scroll
- Active section highlighted in nav via scroll-spy (throttled scroll listener)
- Form inputs: floating labels, 2 px blue bottom border on focus
- Buttons: ripple effect centered on click (CSS ::after pseudo)
- Image lazy-loading with `loading="lazy"` & low-quality placeholder
- Prefers-color-scheme: dark variant (auto-switch via CSS variables)
