# Build brief — an original marketing website in the taste of VinFast
> Reference: https://vinfastauto.us · UIDiscovery: https://uidiscovery.com/sites/vinfast · captured 2026-09-23 at a 1440px desktop viewport (+ 390px iPhone shots) · [full page](https://uidiscovery.com/media/captures/vinfast/full.webp) · [scroll video](https://uidiscovery.com/media/captures/vinfast/preview.mp4)
## 1. Goal
Build an original marketing website for **[the user's brand]** that feels as considered as VinFast — 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 VinFast: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse VinFast'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
- VinFast (vinfastauto.us): Technology marketing website, dark, colorful.
- 9 sections: Hero → Features → Statement → Content → Features → Showcase → Content.
- Spacing: about a screen per idea (median section ≈656px).
- Hero headline: 6 words — short and punchy; keep yours under ~9.
- Type: one family (Mulish). Imagery: mostly photography, some typography with little or no imagery.
## 4. Page structure (top to bottom)
### 1. Hero — state what the product is and for whom in one glance, and offer the primary action.
- Layout: headline-led stack: eyebrow → H1 → supporting line → actions, with a visual beside or below. About one full screen (900px at 1440), page background; 1 image/graphic; one primary button.
- Slots: Eyebrow / announcement pill (optional); H1 (~6 words, like the reference); Supporting line, 1–2 sentences; One primary action; Hero visual (see image plan).
- Topic (tone/length only — never reuse): “Meet The All-New VinFast DrgnFly eBike”
- [Screenshot](https://uidiscovery.com/media/captures/vinfast/s-01.webp) · imagery: slot 1
### 2. Features — explain the key benefits, grouped so each can be scanned in seconds.
- Layout: section title over a grid or alternating rows of benefit items. Half to one screen (663px at 1440), page background; 17 image elements (icons, logos, product UI — not 17 photos); 9 buttons (tabs, toggles or per-card actions), 15 links (link lists / navigation).
- Slots: Section title (~4 words, like the reference); 3 items: icon or visual + short title + 1–2 line description; Primary + secondary action.
- Topic (tone/length only — never reuse): “Explore the VinFast Family”
- [Screenshot](https://uidiscovery.com/media/captures/vinfast/s-02.webp) · imagery: slot 2
### 3. Statement — a large-type moment that sets tone and pace.
- Layout: oversized typography with lots of space. Compact band (248px at 1440), own dark band #000000; no images (type-led); no interactive controls.
- Slots: Heading (~8 words, like the reference); Body copy.
- Topic (tone/length only — never reuse): “The perfect blend of premium quality & comfort”
- [Screenshot](https://uidiscovery.com/media/captures/vinfast/s-03.webp)
### 4. Content — supporting content that deepens one idea.
- Layout: text + media block. Half to one screen (720px at 1440), own dark band #000000; 2 image/graphics; 2 text links instead of buttons.
- Slots: Heading; Body copy; Supporting visual (see image plan); Text link action.
- [Screenshot](https://uidiscovery.com/media/captures/vinfast/s-04.webp) · imagery: slot 3
### 5. Features — explain the key benefits, grouped so each can be scanned in seconds.
- Layout: section title over a grid or alternating rows of benefit items. Tall, ≈1.9 screens (1668px at 1440), own light band #fdfdfd; 12 images/icons (a set of cards or a small gallery); 3 text links instead of buttons; 6 headings → ~5 items under a title.
- Slots: Section title (~3 words, like the reference); 5 items: icon or visual + short title + 1–2 line description; Text link action.

## 5. Design system
### Colour
| Role | Hex | Use | Contrast on background |
|---|---|---|---|
| background | `#1464f4` | page background | — |
| foreground | `#ffffff` | body text, headings | 5.0:1 |
| accent | `#ffffff` | none captured — monochrome. Primary buttons invert (foreground fill, background text); add your brand colour only for small highlights | — |
| surface | `#ff0000` | cards, inputs, alternate bands | text on it 4.0:1 |
| muted | `#fdfdfd` | secondary text, borders | 5.0:1 |
Captured palette: `#1464f4` `#ffffff` `#151515` `#3c3c3c` `#fdfdfd` `#ff0000`. Section bands top→bottom: `#000000` → `#fdfdfd`. 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: #1464f4;
--foreground: #ffffff;
--accent: #ffffff;
--surface: #ff0000;
--muted: #fdfdfd;
--font-heading: "Mulish", ui-sans-serif, system-ui, sans-serif;
--font-body: "Mulish", 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: **Mulish** (Google Fonts) — reference uses Mulish. Free to use — load it directly.
- Body: same family — a single-family system; create contrast with size and weight, not a second face.
- 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 ≈656px tall at 1440 (median; range 211–1668px, 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 1 time 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
Confident colour blocks — let full-bleed colour bands and big shapes carry the personality. 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 9 section screenshots: mostly **photography**, some typography with little or no imagery (dark, warm, Technology). Still glance at the linked screenshots to match the exact mood.
### Slot 1 · 1. Hero → photography
- Photography, seen in the capture (automobile, vehicle, car). (measured from the screenshot) Count: 1. Aspect: 16:9 full-bleed (or 21:9). Look first: [ref 1](https://uidiscovery.com/media/captures/vinfast/s-01.webp)

### Slot 4 · 5. Features → photography
- Photography, seen in the capture (people, adult, vehicle). (measured from the screenshot) Count: a set of ~12 in one consistent style. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/vinfast/s-05.webp)
- **Stock** — “3d glass shapes render close up dark”: [Unsplash](https://unsplash.com/s/photos/3d-glass-shapes-render-close-up-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/3d%20glass%20shapes%20render%20close%20up%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/3d%20glass%20shapes%20render%20close%20up%20dark/?orientation=horizontal)

Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 5 · 6. Showcase → photography
- Photography, seen in the capture (dashboard, headphones, dial). (measured from the screenshot) Count: a set of ~4 in one consistent style. Aspect: 16:10. Look first: [ref 1](https://uidiscovery.com/media/captures/vinfast/s-06.webp)
- **Stock** — “minimal desk with laptop close up dark”: [Unsplash](https://unsplash.com/s/photos/minimal-desk-with-laptop-close-up-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/minimal%20desk%20with%20laptop%20close%20up%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/minimal%20desk%20with%20laptop%20close%20up%20dark/?orientation=horizontal)
- **Generate** — `Photograph: minimal desk with laptop close up. Composition: centred subject with even space around it. Lighting: low-key, moody directional light with deep shadows. Warm colour grade that sits on #1464f4, #ffffff, #ff0000. 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)** — 3. Statement, 7. Content, 8. Content, 9. Content: 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.
### 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 #fdfdfd and #ff0000 on a #1464f4 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 16:9. 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)
- **illustration** — generate `Flat vector illustration: abstract gradient mesh, friendly simplified shapes, limited palette of #1464f4, #ffffff, #ff0000 plus one soft neutral, plenty of empty background, consistent line weight, warm mood. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“technology flat illustration” on Unsplash](https://unsplash.com/s/photos/technology-flat-illustration?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).
