Design a light-mode web interface screen: crisp morning air with chilled juice, buoyant pill shapes, and floating tropical photorealism on pristine white.
LAYOUT
Vertical single-page promotional stack. Begins with an unpinned top bar (logo left, flat links center, pill contact right), followed by a 60/40 hero split (text/CTA left, floating 3D composition right). Transitions to a centered 3-step linear flow connected by dashed lines, flowing into a balanced 3-column prize grid and subsequent winner list.
PALETTE (use these exact hex values)
- #FFFFFF — Canvas White: Global background canvas, prize card fill, and default button foreground
- #2563EB — Cobalt Punch: Primary CTA backgrounds, key headline emphasis, active tabs, and step icon markers
- #EFF6FF — Soft Sky Tint: Hero badge fill, step circle backgrounds, and icon container tint
- #0F172A — Deep Slate: Primary typography, titles, and high-emphasis display copy
- #64748B — Muted Slate: Supporting descriptions, sub-labels, and inactive navigational states
- #E2E8F0 — Clean Border: Hairline card strokes, pill outline buttons, and connector dashed lines
- #ECFDF5 — Mint Stock: Inventory pill background for stock indicators
- #059669 — Emerald Alert: Stock counter text indicating remaining available units
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Urbanist), weights 400/500/600/700. Sizes 12px caption, 14px body-sm, 15px body, 18px body-lg, 24px heading, 32px heading-lg, 44px display. Tracking -0.03em for display, 0 for body. Plus Jakarta Sans delivers an open, buoyant, and trustworthy contemporary tone. The tight tracking on the display size (-0.03em) keeps bold headlines assertive and cohesive, while generous line heights (1.5-1.6) on body copy ensure promotional fine print remains effortless to scan.
GEOMETRY & SPACING
Corner radii — cards 20px, links 2px, inputs 999px, buttons 999px. Spacing on a 8px unit, 24px gaps, 96px between sections, 1200px container, airy density.
DEPTH
Depth is achieved purely through photorealistic 3D product renders casting soft ambient occlusion onto the white plane. Cards and UI components eschew heavy raster box-shadows, remaining flat with crisp 1px borders (#E2E8F0) to let imagery pop forward.
IMAGERY
Photorealistic, hyper-detailed commercial product 3D rendering featuring dynamic floating elements (cut pineapples, paper cups, floating leaves, lids). Visuals must be bright, studio-lit with clean cast shadows, and isolated cleanly from the background without cluttered photographic scenes.
SIGNATURE DETAIL — the thing that makes this design itself
The asymmetric organic hero mask containing dynamic floating fruit and beverage renders bursting into pure white space, paired directly with the cobalt accent line under centered section headers.
MUST
- Keep card backgrounds pure white with a delicate 1px border (#E2E8F0) instead of grey surface fills.
- Isolate product imagery on clear or white backgrounds with natural soft directional shadows.
- Use full pill radii (999px) for all primary buttons, ghost buttons, and counter badges.
- Include the signature 32px cobalt bar under centered secondary and tertiary section titles.
AVOID
- Never use dark backgrounds or saturated gradient cards that disrupt the pure white canvas.
- Do not use sharp or small 4px corner radii on buttons or promotional cards.
- Avoid placing heavy drop shadows beneath cards; lean into hairline strokes for separation.
- Do not color entire headings in cobalt; only color the leading keyword for intentional focus.
OUTPUT
Render as a clean, pixel-crisp UI design at roughly 1712:3840. Flat vector rendering, real legible text, no browser chrome, no device mockup frame, no watermark, no lorem ipsum placeholder blocks. 在 DraPub 中尝试
