Analyse du design system

basecamp.com

basecamp.com is built on a mid-dark canvas (oklch(0.9822 0.0118 313.22)). The system uses rgb(35, 119, 210) as the high-saturation accent for primary actions. Graphik as the primary typeface. A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy. Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

À faire / À éviter

23 règles applicables, verbatim de la spec

À faire

Use Canvas (`#fcf7ff`) as the page background — it's intentionally not pure white

Use Ink (`#29353c`) for text — not pure black, it's warmer and more readable

Use Graphik as the primary typeface — it defines the brand personality

Keep font weights between 400-600 — the system uses a narrow weight range for subtle hierarchy

Use negative letter-spacing (-0.942872px) at display sizes for compressed, editorial headlines

Use the extracted shadow patterns for elevation — they are tuned to match the brand palette

Use Blue (`#2377d2`) as the primary accent — it's the brand's signature interactive color

Use small 5.71428px radius for buttons — this design system uses subtle rounding, not pill shapes

Maintain nav height at 76.1875px — consistent vertical space for the navigation bar

Use a single primary CTA in the hero — the design intentionally avoids choice paralysis

Use a 4-column grid on desktop — density matters for this content type

Place 2 pricing tiers side-by-side on desktop — direct comparison is the value prop

Lay out testimonials in a grid (12+ items) — quantity signals scale and trust

À éviter

Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity

Don't use pure black (`#000000`) for text — the near-black adds warmth

Don't substitute with generic sans-serif or serif — the custom font carries the brand

Don't reach for weight 700 (bold) or above — 600 is the heaviest weight this design paints

Don't increase letter-spacing on headings — the type is designed to run tight at scale

Don't invent new shadow values — use only the extracted shadow levels

Don't introduce additional saturated accent colors — the palette is intentionally controlled

Don't over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners

Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence

Don't make the nav sticky — this design lets it scroll away to maximize content focus
