# Build brief — an original hero section in the taste of Semrush

## Goal
Build an original hero section for **[the user's brand]**. Its job: state what the product is and for whom in one glance, and offer the primary action.
## Originality rules
- Never reuse Semrush'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]).
## Layout
- Pattern: headline-led stack: eyebrow → H1 → supporting line → actions, with a visual beside or below. Half to one screen (525px at 1440), own light band #ffffff; no images (type-led); inline form (1 field, e.g. email capture), primary + secondary button.
- Content slots: Eyebrow / announcement pill (optional); H1 (~5 words, like the reference); Supporting line, 1–2 sentences; Primary + secondary action; No image — let type and colour carry it.
- Reference headline (tone/length only — never reuse): “Be found everywhere search happens”
- Responsive: stack columns below 768px keeping the order heading → body → action → visual; test at 390 / 768 / 1440px.
## Design tokens
- Colour: section background `#ffffff`, text `#ffffff` (1.0:1), accent `#c190ff` (2.4:1), surface `#181e15`, muted `#d1d2d5`. Keep the mood; swap the accent for the user's brand colour.
- Type: headings **Inter** (stand-in for Lazzer), body **Inter**.
- Shape: Radii and shadows weren't measured. Read exact corner radius, border and shadow treatment from the screenshots.

## Imagery
Best guess: mostly **typography with little or no imagery** (dark, cool, Marketing). Inferred from element counts, colours and industry — not from the pixels — so open the linked screenshots and match the real style before sourcing anything.
### Slot 1 · Hero → no imagery (type-led)
- No <img> elements captured. Any background graphic is CSS, canvas or video — check the screenshot. Count: 1. Aspect: 3:2. Look first: [ref 1](https://uidiscovery.com/media/captures/semrush/s-01.webp)
- 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:
- **photography** — generate `Photograph: abstract gradient mesh. Composition: wide shot, subject off-centre to one side, generous clean negative space for the headline. Lighting: low-key, moody directional light with deep shadows. Cool colour grade that sits on #ffffff, #c190ff, #181e15. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 3:2. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **abstract 3D / gradient** — generate `Abstract 3D render: soft, glossy glass-like shapes and a smooth gradient in #c190ff and #d1d2d5 on a #181e15 background. Lighting: low-key, moody directional light with deep shadows; cool 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.`
- **Licences:** check each stock image's licence page (Unsplash/Pexels licences, Pixabay Content License), credit when asked, avoid logos, brands and identifiable people; check your image model's commercial terms; never reuse the reference's own images or logos.
## 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.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
If you use Next.js + Tailwind: one server component for the section, next/image with explicit sizes, next/font for type, Tailwind v4 @theme tokens from the link above.
