Tokens are the variables of the design language: colors, font sizes, spacing, radii, shadows, and animation durations are all named as --lh-* CSS variables, and components consume the names instead of hardcoding values. Re-skinning is just swapping tokens.

--lh-primary-color : # 2B4C7C ;
--lh-text-primary : rgba ( 0 , 0 , 0 , 0.88 );
--lh-border-color : # e5e6eb ;
--lh-text-primary : # E8E0D8 ;
--lh-border-color : # 3A3530 ;
Dark mode is an override layer , not a separate set: it only writes the 118 tokens that need to flip; the rest keep their light values.
$lh-primary-color : # 2B4C7C !default ;
$lh-border-radius-base : 6 px !default ;
SCSS variables exist to participate in compile-time computation : color mixing (mix() / shade()), shadow composition (adding multiple shadow layers) — things CSS variables cannot do. The cost is being baked at compile time , so they do not flip automatically in dark mode.
Tokens fall into three tiers — the first two live in the global theme files, the third in each component’s own stylesheet:
// 1. SCSS variables (variables.scss, compile time)
$lh-primary : # 2B4C7C !default ;
$lh-text-primary : # 2C2C2C !default ;
// 2. Global CSS variables (var.scss :root, 190 entries)
--lh-primary-color : #{ $lh-primary } ;
--lh-text-primary : #{ $lh-text-primary } ;
// 3. Component-level variables (the component's own scss, scoped to its BEM root)
--lh-card-bg : var ( --lh-bg-color , # FAF6F0 );
--lh-card-border-radius : calc ( var ( --lh-border-radius-base , 2 px ) + 2 px );
Key mechanisms:
Tiers 1 and 2 are linked by compile-time interpolation, not a var() chain : the value of --lh-primary-color is baked in at build time from $lh-primary — changing the SCSS variable at runtime has no effect (you must recompile). There is no separate “base palette” tier — no --lh-blue-6 color-step variables exist; semantic tokens are generated directly from the SCSS variables.
Two levers for re-skinning : edit the SCSS variables in variables.scss and recompile (affects every semantic token), or override the :root CSS variables at runtime (what ConfigProvider’s themeVars does — instant, no rebuild).
Tier 3 defaults to tier 2 : component-level variables usually default to a var() reference of a global token (with a fallback), keeping them in sync with the theme while still allowing targeted per-component overrides via themeVars.

(Data is generated by scripts/gen-docs-data.mjs parsing the three token files, with count assertions: 190 light, 118 dark, 188 SCSS — a mismatch raises an error.)
// ConfigProvider's themeVars (shorthand keys get the --lh- prefix auto-completed)
< lh - config - provider :theme - vars = " { 'primary-color': '#1677ff' } " >
Or write CSS at your application entry:
--lh-primary-color : # 1677ff ;
--lh-primary-color-hover : # 4096ff ;
--lh-primary-color-active : # 0958d9 ;
See Runtime Customization .
// Your project entry scss, override before @use
$lh-primary-color : # 1677ff ;
@use ' @lh-ui/share/styles ' ;
!default means “do not override if a value already exists”, so assigning before @use is enough. Note : this only affects the compile-time-baked part; the runtime CSS variables still need to be overridden separately.
The “control-height token initiative” has landed (adding --lh-control-height-mini/small/medium/large/x-large,
with button / select / input-number / cascader / tree-select / date-picker / time-picker /
input all switched to the tokens, input changing from padding-derived to fixed height, and the
asymmetric padding-top: 16px for has-label, the fixed checkbox-check offset, and the duplicated
translate(-50%,-50%) hardcoding in switch all fixed along the way). What remains:
Inconsistent size steps between spinner and icon (small 16 vs 14, medium 24 vs 16, etc.). Changing either side ripples across the whole library (message / notification / loading / every icon). Trigger condition: visual complaints about mixing LhIcon / LhSpinner in the same slot; at that point it gets its own project.
Misaligned size steps: select / switch only have 3 steps, date / time-picker validators are narrowed, tree-select / rate / segmented / pagination have no size, and mini and x-large are barely drawn in the CSS layer (only avatar in the whole library has x-large). This is an API-layer change, decoupled from the height tokens.
Components must not declare --lh-* on their own : they may only consume via var(--lh-*, fallback) (a red line in the root AGENTS.md). New tokens go in var.scss.
The fallback is mandatory : var(--lh-primary-color, #1677ff) — if a token is missing there is still an acceptable default; verify:styles item 2 (var fallback) enforces this.
Dark completeness : when adding a token, ask “should this flip in dark mode?” If yes, add the override in var-dark.scss; verify:styles item 7 enforces this.
Tokens whose value looks like #{$lh-foo} are baked at compile time : they do not flip automatically in dark mode and must be explicitly re-pointed (see Dark Mode ).
