@uncinq/css-components

Framework-agnostic CSS component implementations — actual styles built on top of design and component tokens.

What is this?

@uncinq/css-components provides the CSS implementations of common UI components. It sits at the top of the CSS stack:

@uncinq/design-tokens      ← primitive + semantic CSS custom properties
@uncinq/component-tokens   ← component-scoped CSS custom properties
@uncinq/css-base           ← base CSS rules
@uncinq/css-components     ← actual CSS rules (this package)

Each component file contains only CSS rules, using the tokens defined in the two packages above. No JavaScript, no markup opinions — just portable, layered CSS.

CSS cascade layers

All component styles are declared inside @layer components:

@layer config, base, layouts, vendors, components;

This means:

• Components never bleed into base or layout styles
• Project-level @layer components rules always win over these defaults
• Vendors (e.g. Splide) sit below project components but above base

Prerequisites

This package consumes tokens from:

• @uncinq/design-tokens — semantic CSS custom properties
• @uncinq/component-tokens — component-scoped CSS custom properties
• @uncinq/css-base — base CSS rules

Import them before this package:

@import '@uncinq/design-tokens';
@import '@uncinq/component-tokens';
@import '@uncinq/css-base';
@import '@uncinq/css-components';

Installation

npm install @uncinq/css-components
# or
yarn add @uncinq/css-components

Usage — full import

@import '@uncinq/design-tokens';
@import '@uncinq/component-tokens';
@import '@uncinq/css-base';
@import '@uncinq/css-components';

Usage — per component

@import '@uncinq/design-tokens';
@import '@uncinq/component-tokens';
@import '@uncinq/css-base';
@import '@uncinq/css-components/css/component/nav.css';
@import '@uncinq/css-components/css/component/pagination.css';
