The style

A quiet, refined dark language for builders. A charcoal canvas with warm parchment-white text, big headlines in a light-weight grotesk, and very little colour. Parchment pills carry the main action, graphite pills and outlines sit beside them, and large softly rounded panels hold the product. Motion is slow and deliberate, with a strong ease in and out.

40px pills with 14px labels: parchment #E9EBDF with a dark label for the main action, graphite #242424 or an outlined pill for the second.

Layout

1416px container · 12 columns · 24px gutters

Patterns

  • Wide single-column hero with generous vertical rhythm between sections.
  • Twelve-column grid; content blocks usually span 4, 6 or 8 columns.
  • Full-bleed bands for feature sections, inner content capped at the container.
  • Reading text limited to roughly 65–72 characters per line.

Responsive principles

  • Below md, grids collapse to a single column and side gutters drop to 16px.
  • Type steps above h2 scale down one step on small screens.
  • Navigation collapses to a disclosure menu below lg.
  • Touch targets stay at least 44×44px on every breakpoint.

07

Motion

Durations and easing curves. Previews respect your reduced-motion setting.

  • fast
    110ms
  • base
    190ms
  • slow
    310ms
  • ease-standard

  • ease-enter

  • ease-exit

Principles

  • Motion is measured and calm, easing into place rather than snapping.
  • Animate opacity and transform only; avoid animating layout.
  • Respect prefers-reduced-motion by replacing movement with instant state changes or fades.
