* design-systems/uber/tokens.css
|
|||
|
|
*
|
|||
|
|
* Structured token bindings for the "Uber" brand — bold black-and-white,
|
|||
|
|
* pill-shaped everything, tight urban energy.
|
|||
|
|
*
|
|||
|
|
* Brand identity in three sentences:
|
|||
|
|
* 1. Pure black (#000000) and pure white (#ffffff) — not near-black or
|
|||
|
|
* off-white; the stark duality IS Uber; no warmth, no tint, no mid-tone
|
|||
|
|
* grays in the UI chrome (only #4b4b4b secondary and #afafaf tertiary).
|
|||
|
|
* 2. UberMove (proprietary geometric sans) at 700 for all headings — bold
|
|||
|
|
* as a billboard; UberMoveText at 400–500 for body/UI; two fonts with
|
|||
|
|
* strict roles; no decorative type treatment whatsoever.
|
|||
|
|
* 3. Pill-shaped everything: 999px radius on all buttons, chips, and nav
|
|||
|
|
* items — unmistakably Uber; whisper-soft shadows (0.12–0.16 opacity)
|
|||
|
|
* for the bare minimum card lift; gradient-free, flat color blocks.
|
|||
|
|
*
|
|||
|
|
* Schema decisions:
|
|||
|
|
* - --bg: #ffffff; --surface: #ffffff (cards defined by shadow, not color).
|
|||
|
|
* - --surface-warm: #f8f8f8 (thread panels / hover state — barely there).
|
|||
|
|
* - --fg: #000000 (true black); --fg-2: #000000 (same).
|
|||
|
|
* - --muted: #4b4b4b (body gray — secondary text); --meta: #afafaf.
|
|||
|
|
* - --border: #000000 (functional only — inputs); --border-soft: none.
|
|||
|
|
* - --accent: #000000 (black IS the primary CTA color in B&W system).
|
|||
|
|
* - --accent-on: #ffffff; --accent-hover: #e2e2e2 (hover gray on white).
|
|||
|
|
* - --tracking-display: normal (no letter-spacing — functional typography).
|
|||
|
|
* - --leading-tight: 1.23 (52px display hero line-height).
|
|||
|
|
* - h2 (36px) → 1.22; h3 (24px) → 1.33 per DESIGN.md type table.
|
|||
|
|
* - --radius-sm: 999px (full pill for all CTAs per brand identity).
