Design a light-mode web interface screen: breezy azure canvas anchoring global wanderlust through crisp modular white cards and electric cobalt accents.
LAYOUT
The interface is structured on an asymmetric split: a fixed 240px utility sidebar on the left, paired with a wide fluid content canvas on the right. Content progresses vertically from a top utility navbar into an expansive hero section with left-aligned typographic pitch and right-aligned landmark montage. A consolidated search engine spans across the lower third of the hero, immediately followed by horizontal destination carousels.
PALETTE (use these exact hex values)
- #FFFFFF — Main Canvas Light: Primary surface for content cards, top header bar, and booking input containers.
- #F8FAFC — Sidebar Surface: Muted neutral backdrop for the left navigation rail and inactive utility panels.
- linear-gradient(180deg, #DCEEFE 0%, #F5F9FF 60%, #FFFFFF 100%) — Sky Gradient Hero: Background atmosphere framing the hero landmark composition and heading copy.
- #0066FF — Cobalt Brand: Core action buttons, active navigation indicator pills, and key interactive highlights.
- #EBF3FF — Soft Ice Blue: Selected sidebar item fill, hero subhead pill background, and icon badge backing.
- #0F172A — Deep Slate Ink: High-priority display headlines, destination labels, and major section titles.
- #64748B — Muted Slate Grey: Navigation links, descriptive body copy, input placeholders, and inactive tab labels.
- #10B981 — Mint Emerald: Destination card pricing highlights and promotional callout tags.
- #F59E0B — Warm Gold: Star rating icon fills alongside review metrics on destination preview cards.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, Manrope, DM Sans), weights 400/500/600/700/800. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 20px subheading, 24px heading, 44px display. Tracking -0.03em at display, 0em at body. The typographic tone is upbeat, contemporary, and frictionless, relying on an open geometric sans-serif (Plus Jakarta Sans or Inter). Bold weights (700-800) at large scale create energetic commercial impact in the hero headline, while medium weights (500) provide high legibility across dense booking forms. Tight display letter-spacing (-0.03em) keeps large headlines sharp and modern.
GEOMETRY & SPACING
Corner radii — cards 20px, links 999px, inputs 12px, buttons 12px. Spacing on a 8px unit, 20px gaps, 48px between sections, 1440px container, comfortable density.
DEPTH
Depth relies on soft, atmospheric diffusion rather than physical layering. Surfaces float using wide-spread, low-opacity shadows such as `0 12px 32px -4px rgba(15, 23, 42, 0.06)`, simulating gentle natural light. Content cards remain mostly flat with clean 1px border definition, lifting distinctly only when hovering or serving as a floating search chassis.
IMAGERY
Photography consists of high-key, sunlit travel destinations captured under clear blue skies with authentic color saturation. The hero uses a composite cut-out montage of global architectural landmarks (Statue of Liberty, Sydney Opera House, Mayan pyramids, Pagodas, Eiffel Tower) that blend directly into the cloudless gradient sky. Avoid moody, desaturated, or grainy editorial photography.
SIGNATURE DETAIL — the thing that makes this design itself
The panoramic sky montage merging world landmarks directly into an airy azure gradient, paired with a floating white booking pill bar that bridges the hero visual with actionable discovery. It loses its identity if landmarks are boxed into separate cards or if the sky gradient is replaced by a flat solid color.
MUST
- Anchor primary calls-to-action with saturated cobalt blue (#0066FF) and white typography.
- Maintain high corner radii (16px-20px) on interactive containers and visual destination cards.
- Blend destination hero photowork into the background canvas with soft bottom white vignetting.
- Use 11px to 13px muted slate text for contextual metadata and secondary form field labels.
AVOID
- Do not introduce sharp 0px or square corners; everything relies on welcoming curvature.
- Avoid harsh black drop shadows; use diffused slate tones below 8% opacity.
- Do not use saturated backgrounds for the main canvas—keep surfaces light and sky-tinted.
- Never hide pricing highlights in plain text; emphasize figures with vibrant mint or emerald tones.
