Design a light-mode web interface screen: crisp cobalt utility framed by mindful vector warmth and structured saas navigation.
LAYOUT
The frame uses a two-tier layout: a rigid 72px left utility sidebar running full-height, paired with an open, fluid application canvas. The primary canvas begins with a light 64px header, followed by a 50/50 two-column hero split (editorial copy left, vector illustration right). The page concludes with an anchored, three-column feature card tray spanning the lower content width.
PALETTE (use these exact hex values)
- #f8fafc — Canvas Base: Overall viewport background outside the primary content frame and sidebar canvas
- #ffffff — Surface White: Primary content container, feature dock tray, and sidebar panel fill
- #2b59ff — Electric Cobalt: Primary CTA button, active navigation indicator line, logo glyph, and primary hero accents
- #0f172a — Deep Slate: Display headings, logo wordmark, and prominent feature titles
- #64748b — Muted Slate: Hero paragraph copy, inactive navigation labels, and secondary metadata descriptions
- #f59e0b — Solar Amber: Warm vector focal points including the hero lightbulb and character garment
- #eef2ff — Soft Indigo Tint: Background fill for the hero category pill badge and icon badge containers
- #f1f5f9 — Border Subtle: Hairline vertical divider separating the sidebar from the main presentation viewport
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Public Sans), weights 400/500/600/700/800. Sizes 11px caption, 13px body-sm, 15px body, 18px body-lg, 24px subheading, 52px display. Tracking -0.02em at display, 0.05em on caps pills. Plus Jakarta Sans delivers a clean, modern, and mathematically balanced tone that feels authoritative yet approachable. The bold display weights (-0.03em tracking) lend an enterprise-grade posture to the headline, while the medium body weights provide high legibility for product descriptions. Inter or DM Sans serve as effortless drop-in replacements without loss of character.
GEOMETRY & SPACING
Corner radii — cards 18px, links 4px, inputs 10px, buttons 12px. Spacing on a 8px unit, 24px gaps, 64px between sections, 1280px container, comfortable density.
DEPTH
Depth is communicated almost entirely through flat surface layering and hairline borders rather than blurred drop shadows. The bottom feature tray and sidebar sit flush or with an ultra-diffuse 0 4px 20px rgba(15, 23, 42, 0.03) shadow that is nearly imperceptible. This creates a crisp architectural separation without visual clutter.
IMAGERY
The visual language uses clean, vector line-and-flat-color illustrations depicting mindfulness and modern digital productivity (e.g., meditating figure seated on a laptop with a blooming lightbulb). Forms are soft, stylized, and optimistic. Stock photography or hyper-detailed 3D renders are strictly prohibited as they clash with the calm vector clarity.
SIGNATURE DETAIL — the thing that makes this design itself
The distinctive integration of a full-height utility app sidebar directly framing an editorial marketing hero with a bottom docked feature tray. To execute properly, ensure the left sidebar remains minimalist with 24px outlined icons, while the hero illustration balances the tech-heavy interface with warm amber mindfulness motifs.
MUST
- Anchor high-intent actions with solid cobalt blue (#2b59ff) paired with white text.
- Maintain generous 48px to 64px negative space around the hero headline.
- Use 999px pill geometry for metadata tags and secondary status pills.
- Restrict warm accents (#f59e0b) to illustrative elements and conceptual emphasis.
AVOID
- Do not introduce dark-mode heavy cards or saturated solid backgrounds to the main layout.
- Never use sharp, 0px border radii on buttons, docks, or badge elements.
- Avoid photorealistic imagery; preserve the flat, conceptual vector narrative aesthetic.
- Do not clutter the vertical sidebar with text-heavy link descriptions.
