Theming

Design tokens in OKLCH, mapped to Tailwind utilities. One stylesheet controls every component.

A ZardUI theme is a set of CSS variables in src/styles.css . Each one is mapped to a Tailwind color through @theme inline , so --primary becomes bg-primary . Redefining the variable under .dark — or under any container class — retints every component underneath it, with no rebuild and no per-component configuration.

There are three ways to get a theme:

Run the CLI.zard-cli init writes the whole file and asks which base color you want — see Installation .
Copy the CSS. The complete stylesheet is in How it works , explained line by line.
Build your own. The theme generator gives you every token with a live preview and exports finished CSS.

How it works

This is the whole file, exactly as zard-cli init writes it for the Neutral base color. Paste it into src/styles.css and every component is themed.

Line by line

Nine parts, in the order they appear above. Each one earns its place — the last line of every entry says what breaks without it.

@layer ng-icon, theme, base, components, utilities;
Cascade layer order
Declaring the layers up front fixes their priority. ng-icon comes first, so it has the lowest weight — @ng-icons/core ships its rules inside @layer ng-icon.
Without it
Icon styles win over your utilities: text-primary on an <ng-icon> stops changing its color.
@import 'tailwindcss';
TailwindCSS itself
Pulls in preflight, the default theme and the utility engine. Everything below extends it.
Without it
No utility class resolves at all.
@import './app/shared/core/css/tailwind';
ZardUI's core stylesheet
Defines the data-* custom variants (data-open, data-checked, data-selected, data-disabled, data-active, data-horizontal, data-vertical) and the accordion and caret keyframes, and imports css/utilities.css — where no-scrollbar, scroll-fade and shimmer live. The path follows the core alias in components.json.
Without it
The 64 data-*: classes the library relies on silently compile to nothing — open/closed states, checked switches and selected menu items stop reacting. animate-caret-blink, no-scrollbar, scroll-fade and shimmer also disappear.
@plugin "tailwindcss-animate";
Enter/exit animations
Provides animate-in, animate-out, fade-*, zoom-* and slide-in-from-*.
Without it
Dialogs, sheets, popovers and dropdowns appear and vanish with no transition — over 50 classes across the library stop resolving.
@custom-variant dark (&:is(.dark *));
Class-based dark mode
Binds the dark: variant to a .dark ancestor instead of prefers-color-scheme. That is what lets ZardDarkMode flip the theme by toggling one class on <html>.
Without it
dark: follows the OS setting only. The theme toggle stops working and the .dark block below never applies.
:root { --background: oklch(1 0 0); … }
Light values
The raw color of every token, in OKLCH. Plain CSS variables — no Tailwind involved yet.
Without it
Every token resolves to nothing and components render unstyled.
.dark { --background: oklch(0.145 0 0); … }
Dark overrides
Redefines the same variables under .dark. Only the values change — no component knows which mode is active.
Without it
Dark mode keeps the light palette.
@theme inline { --color-primary: var(--primary); … }
Tokens → Tailwind utilities
Turns each token into a color utility: --color-primary is what makes bg-primary exist. inline is the important word — it makes Tailwind emit var(--primary) in the output instead of copying the value, so the .dark override still applies at runtime.
Without it
Without the block, bg-primary does not exist. Without inline, the light value gets baked into the CSS and dark mode has no effect.
@layer base { * { @apply border-border outline-ring/50; } … }
Global defaults
Gives every element the themed border color and focus ring, and paints body with bg-background text-foreground.
Without it
Borders fall back to currentColor, focus rings lose their theme color, and the page background stays white in dark mode.

Why OKLCH and not HSL or HEX?

Lightness is perceptual: the same lightness value looks equally light at any hue, so a palette stays balanced when you shift the hue. Interpolation stays clean — color-mix() and opacity modifiers do not drift toward grey the way HSL does.

Convention

Tokens come in pairs: a surface and the text that sits on it. The background suffix is dropped, so --primary is the surface and --primary-foreground is the text on top of it.

--primary: oklch(0.205 0 0);
--primary-foreground: oklch(0.985 0 0);

Every pair, rendered

These are real utilities on real elements — the contrast you see is the contrast you get.

dark 14.22:1

--secondary--secondary-foreground

dark 17.16:1

Contrast ratios are computed from the Neutral preset. * marks a pair below the 4.5:1 WCAG AA threshold for body text — use it for large or secondary text, not for body copy.

Tokens or raw utility classes?

Prefer tokens. They react to .dark and to scoped overrides on their own:

<div class="bg-background text-foreground">
  <!-- Your ZardUI components here -->
</div>

Raw Tailwind colors work too, but you own every dark-mode variant by hand and lose scoped theming entirely:

<div class="bg-zinc-950 dark:bg-white text-zinc-50 dark:text-zinc-950">
  <!-- Your ZardUI components here -->
</div>

Token reference

All 32 tokens, with their Neutral values in both modes. The Used by column comes from a scan of the library source, so a token marked not used yet really is unused today.

Radius & scale

--radius is the single knob for corner rounding. The four utilities below are derived from it in @theme inline , so changing one value reshapes every component.

--radius :

Dark mode

Dark mode is the .dark block and nothing else. No component knows which mode is active: they all read the same token names, and the values change underneath them.

Two pieces make it work — @custom-variant dark (&:is(.dark *)) binds the dark: variant to a class instead of the OS setting, and something has to put that class on <html> . The ZardDarkMode service does that, and persists the choice.

Customizing

Three things you are likely to want: a new color, a token overridden for one part of the app, and a theme that follows a route.

Adding a new color

Declare the raw value, override it under .dark , then map it — the same three steps every built-in token goes through.

src/styles.css

:root {
  --warning: oklch(0.84 0.16 84);
  --warning-foreground: oklch(0.28 0.07 46);
}

.dark {
  --warning: oklch(0.41 0.11 46);
  --warning-foreground: oklch(0.99 0.02 95);
}

@theme inline {
  --color-warning: var(--warning);
  --color-warning-foreground: var(--warning-foreground);
}

<div class="bg-warning text-warning-foreground">Warning message</div>

Overriding tokens in one scope

Because @theme inline emits var(--primary) instead of a baked-in color, any container can redefine a token for its subtree.

src/styles.css

.theme-brand {
  --primary: oklch(0.55 0.22 264);
  --primary-foreground: oklch(0.98 0.01 264);
  --radius: 1rem;
}

<section class="theme-brand">
  <!-- Every ZardUI component in here picks up the scoped values. -->
  <button z-button>Brand button</button>
</section>

A theme per route

Put the override class on a layout component's host and everything rendered through its outlet inherits it.

src/app/marketing/marketing.layout.ts

import { ChangeDetectionStrategy, Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';

@Component({
  selector: 'app-marketing-layout',
  imports: [RouterOutlet],
  // The class carries the token overrides declared in src/styles.css.
  host: { class: 'theme-brand' },
  template: `<router-outlet />`,
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class MarketingLayout {}

src/app/app.routes.ts

import type { Routes } from '@angular/router';

export const routes: Routes = [
  {
    path: 'marketing',
    loadComponent: () => import('./marketing/marketing.layout').then(m => m.MarketingLayout),
    children: [{ path: '', loadComponent: () => import('./marketing/home.page').then(m => m.HomePage) }],
  },
];

Other color formats

The raw tokens hold plain CSS colors, so RGB, HSL and HEX all work. Keep the @theme inline mapping as it is.

src/styles.css

:root {
  /* OKLCH — what ZardUI ships */
  --primary: oklch(0.205 0 0);

  /* RGB */
  --secondary: rgb(244 244 245);

  /* HSL */
  --accent: hsl(240 5% 96%);

  /* HEX */
  --muted: #f4f4f5;
}

Need the values? The colors page lists the full Tailwind palette in OKLCH, HEX, RGB and HSL.

Troubleshooting

Every entry below is a real failure mode of the setup on this page, with the line that causes it.

Cause: @custom-variant dark (&:is(.dark *)); is missing, so dark: still maps to prefers-color-scheme.
Fix: Add the @custom-variant line above :root, and make sure something puts the .dark class on <html>.

Cause: @theme was used instead of @theme inline. Tailwind copied the light values into the output.
Fix: Use @theme inline. It emits var(--primary) instead of the resolved color, so .dark can still win.

Cause: The core stylesheet is not imported, so the data-* custom variants do not exist.
Fix: Add @import './app/shared/core/css/tailwind'; right after @import 'tailwindcss';.

Cause: @plugin "tailwindcss-animate"; is missing, so animate-in and friends do not resolve.
Fix: Add the @plugin line and install tailwindcss-animate.

Cause: The @layer order is missing or ng-icon is not first, so icon rules outrank your utilities.
Fix: Keep @layer ng-icon, theme, base, components, utilities; as the very first line of the file.

Cause: The variable was declared inside a component stylesheet or a nested selector instead of :root.
Fix: Declare raw values in :root / .dark, and scope overrides deliberately with a container class.
