> Reference: https://www.klaviyo.com · UIDiscovery: https://uidiscovery.com/sites/klaviyo · captured 2026-09-21 at a 1440px desktop viewport (+ 390px iPhone shots) · [full page](https://uidiscovery.com/media/captures/klaviyo/full.webp) · [scroll video](https://uidiscovery.com/media/captures/klaviyo/preview.mp4)
## 1. Goal
Build an original marketing website for **[the user's brand]** that feels as considered as Klaviyo — same structure, rhythm and polish, entirely new identity and content.
## 2. Originality rules
- Build an ORIGINAL design for the user's own brand in the same *taste* as Klaviyo: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse Klaviyo's logo, name, product imagery, illustrations, icons, screenshots or copy. Write new copy for the user's product.
- If the user hasn't said what their product is, ask first (or use clearly marked placeholders like [Brand], [Product], [Audience]).
- Reference screenshots are for looking at, not for embedding or tracing.
## 3. The taste, in short
- Klaviyo (klaviyo.com): Marketing marketing website, dark.
- 12 sections: Hero → Call to action → Features → Content → Statement → Showcase → Integrations → Logo cloud → FAQ → Footer.
- Spacing: about a screen per idea (median section ≈716px).
- Hero headline: 6 words — short and punchy; keep yours under ~9.
- Type: Klaviyo Degular headings over Instrument Sans body. Imagery: mostly typography with little or no imagery, some product UI screenshots/mockups.
## 4. Page structure (top to bottom)
### 1. Hero — state what the product is and for whom in one glance, and offer the primary action.

## 5. Design system
### Colour
| Role | Hex | Use | Contrast on background |
|---|---|---|---|
| background | `#1d1e20` | page background | — |
| foreground | `#ffffff` | body text, headings | 16.7:1 |
| accent | `#ff4b33` | primary buttons, links, highlights — sparingly | 5.0:1 |
| surface | `#1d1e20` | cards, inputs, alternate bands | text on it 16.7:1 |
| muted | `#cbc8c4` | secondary text, borders | 10.0:1 |
Captured palette: `#1d1e20` `#ffffff` `#ff4b33` `#cbc8c4`. Section bands top→bottom: `#ffffff` → `#1d1e20` → `#ff4b33`. Roles are assigned automatically — sanity-check them against the screenshot. Keep the palette's *mood* (dark, warm) and proportions; swap the accent for the user's brand colour.
### Tokens
```css
:root {
--background: #1d1e20;
--foreground: #ffffff;
--accent: #ff4b33;
--surface: #1d1e20;
--muted: #cbc8c4;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Instrument Sans", ui-sans-serif, system-ui, sans-serif;
--radius: 12px; /* calibrate from the screenshot */
}
/* Tailwind v4 — in globals.css after @import "tailwindcss"; */
@theme {
--color-background: var(--background);
--color-foreground: var(--foreground);
--color-accent: var(--accent);
--color-surface: var(--surface);
--color-muted: var(--muted);
--font-heading: var(--font-heading);
--font-sans: var(--font-body);
}
```
### Typography
- Headings: **Inter** (Google Fonts) — reference uses Klaviyo Degular. “Klaviyo Degular” is likely a custom or licensed face. Inter is a neutral stand-in — pick a closer free match by eye from the screenshot.
- Body: **Instrument Sans** (Google Fonts) — reference uses Instrument Sans. Free to use — load it directly.
- Scale (starting point, sizes weren't measured — calibrate against the 1440px screenshot): display clamp(2.75rem, 6vw, 5rem), h2 clamp(1.75rem, 3vw, 2.5rem), h3 1.25rem, body 1rem–1.125rem / 1.6, small 0.875rem. Headings: tight tracking (-0.02em), line-height 1.05–1.15.
### Spacing & rhythm
Sections run ≈716px tall at 1440 (median; range 160–1700px, captures cap at 1700px) — roughly a screen per idea. Start with 96–120px vertical padding per section on desktop and about two-thirds of that on mobile. The background changes 4 times down the page — use band changes to mark chapters. 8px spacing grid, 1200–1280px max content width, 24px (mobile) / 32–48px (desktop) gutters.
### Shape, depth & theme
Radii and shadows weren't measured. Read exact corner radius, border and shadow treatment from the screenshots. Dark-first; for a light mode swap background ↔ foreground, lighten the surface, keep the accent and re-check contrast.
## 6. Imagery plan
Measured from 7 section screenshots: mostly **typography with little or no imagery**, some product UI screenshots/mockups (dark, warm, Marketing). Still glance at the linked screenshots to match the exact mood.
### Slot 1 · 1. Hero → product UI
- Product UI — screenshots or mockups of the app, seen in the capture. (measured from the screenshot) Count: 1. Aspect: 3:2. Look first: [ref 1](https://uidiscovery.com/media/captures/klaviyo/s-01.webp)
- **Stock** — “laptop blank screen minimal desk”: [Unsplash](https://unsplash.com/s/photos/laptop-blank-screen-minimal-desk?orientation=landscape) · [Pexels](https://www.pexels.com/search/laptop%20blank%20screen%20minimal%20desk/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/laptop%20blank%20screen%20minimal%20desk/?orientation=horizontal)
- **Generate** — `Product-shot backdrop for a UI screenshot: smooth dark gradient from #1d1e20 to #1d1e20 with a soft #ff4b33 glow behind the centre, subtle floor shadow, empty centre area where a screenshot will be placed. Lighting: low-key, moody directional light with deep shadows. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people. No UI elements.`
- Build the UI itself in HTML/CSS with realistic sample data from YOUR product (or screenshot your real app). Don't generate UI as an image and don't reuse the reference's screenshots. Stock/AI is only for the backdrop or device frame.
### Slot 2 · 5. Content → illustration (uncertain)
- Light Marketing section with a few graphics — illustration, icon art or a product shot. Count: a set of ~15 in one consistent style. Aspect: 4:5. Look first: [ref 1](https://uidiscovery.com/media/captures/klaviyo/s-05.webp)
- **Stock** — “technology flat illustration”: [Unsplash](https://unsplash.com/s/photos/technology-flat-illustration?orientation=portrait) · [Pexels](https://www.pexels.com/search/technology%20flat%20illustration/?orientation=portrait) · [Pixabay](https://pixabay.com/images/search/technology%20flat%20illustration/?orientation=vertical)
- **Generate** — `Flat vector illustration: abstract gradient mesh, friendly simplified shapes, limited palette of #ffffff, #ff4b33, #1d1e20 plus one soft neutral, plenty of empty background, consistent line weight, warm mood. Aspect ratio 4:5. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- Uncertain: this could equally be photography, a product shot or icon art — open the reference screenshots and match what you see.
### Slot 3 · 8. Showcase → photography
- Photography, seen in the capture (people). (measured from the screenshot) Count: 1–3 key visuals; the rest are icons/avatars. Aspect: 16:10. Look first: [ref 1](https://uidiscovery.com/media/captures/klaviyo/s-08.webp)
- **Stock** — “3d glass shapes render wide shot dark”: [Unsplash](https://unsplash.com/s/photos/3d-glass-shapes-render-wide-shot-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/3d%20glass%20shapes%20render%20wide%20shot%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/3d%20glass%20shapes%20render%20wide%20shot%20dark/?orientation=horizontal)
- **Generate** — `Photograph: 3d glass shapes render wide shot. Composition: centred subject with even space around it. Lighting: low-key, moody directional light with deep shadows. Warm colour grade that sits on #1d1e20, #ff4b33. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 16:10. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **No imagery (type-led)** — 2. Call to action, 3. Features, 4. Content, 6. Content, 7. Statement, 11. FAQ: No imagery needed — type, spacing and colour do the work. If the screenshot shows a background graphic, rebuild it in CSS (gradient, grid, noise) or a short muted video, not a stock photo.
- **Logos** — 9. Integrations, 10. Logo cloud: Never generate or stock-source logos. Use your real customers'/partners' marks with permission (monochrome, equal height), or neutral wordmark placeholders until you have them. Integration icons: each tool's official brand kit (Simple Icons is a quick start; trademarks still apply).
- **Icons** — 12. Footer: Use one open-source icon set at one stroke weight — Lucide, Phosphor or Heroicons (MIT) — tinted with the text or accent token. Social icons: Simple Icons.
### If the screenshots show a different style
Open the refs first and name what you actually see (photo / product UI / illustration / abstract gradient or 3D / type only). If it differs from the guess, switch routes — UI is built in code, type-only needs no image, otherwise:
- **abstract 3D / gradient** — generate `Abstract 3D render: soft, glossy glass-like shapes and a smooth gradient in #ff4b33 and #cbc8c4 on a #1d1e20 background. Lighting: low-key, moody directional light with deep shadows; warm tone. Minimal and calm, generous negative space on one side for text. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“abstract dark gradient 3d” on Unsplash](https://unsplash.com/s/photos/abstract-dark-gradient-3d?orientation=landscape) (same query works on Pexels/Pixabay)
- **Licences:** Unsplash and Pexels images are free for commercial use under their own licences; Pixabay under the Pixabay Content License. Check each image's page before use, credit the photographer when asked (good practice anyway), and skip images showing logos, trademarks, branded products or identifiable people without a release.
- **AI generation:** the prompts work with any image model (GPT Image, Imagen, Flux, Midjourney, Firefly, SDXL…) — check its commercial-use terms. Never put the reference brand's name or “in the style of <brand>” in a prompt.
- **Never** download, trace or re-host the reference's own images, illustrations, product shots or logos.
## 7. Build steps
1. Confirm brand, product, audience and the primary action with the user.
2. Set up the tokens (CSS variables / Tailwind @theme) and load the fonts.
3. Build the sections in order, mobile-first, with each reference screenshot open.
4. Write original copy for every slot — match length and tone, never the words.
5. Source every image via the imagery plan (stock or generated); compress it and record credits.
6. Run the checklist at 390 / 768 / 1440px and fix what fails.
## 8. Acceptance checklist
- [ ] Responsive at 390px, 768px and 1440px — no horizontal scroll, tap targets ≥ 44px on mobile.
- [ ] Colour contrast WCAG AA: 4.5:1 body text, 3:1 large text and UI; visible focus states; full keyboard navigation.
- [ ] Semantic HTML: one <h1>, ordered headings, landmarks (header/nav/main/footer), labelled form fields, alt text on meaningful images.
- [ ] Performance: modern image formats with width/height set, lazy-load below the fold, ≤ 2 font families with font-display: swap, LCP < 2.5s.
- [ ] prefers-reduced-motion respected; animations under ~300ms and never blocking content.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
## 9. If you use Next.js + Tailwind
Paste the @theme block into globals.css, load fonts with next/font/google, make each section a server component in components/sections/, use next/image with explicit sizes, and keep client components for interactive bits only (menus, toggles, accordions).
