SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Inconsistent visual styling leads to fragmented brand experience and maintenance overhead. This Skill provides a single source of truth for all CSS visual values, eliminating hard‑coded colours, sizes, and other UI inconsistencies.

Core Features & Use Cases

Token Architecture: Defines colour, typography, spacing, shadow, radius, and breakpoint tokens as CSS custom properties in src/index.css.
Enforcement Rules: Requires all component styles to reference these tokens, forbids !important except for third‑party overrides, and mandates theme switching via data attributes.
Practical Use Case: When a frontend developer creates a new product card component, they reference the design system to ensure the card uses the predefined colour palette, spacing scale, and shadow levels, guaranteeing visual consistency across the application.

Quick Start

Load the css-design-system skill before editing any CSS files to apply the standardized design tokens.

FAQPage Schema

How do I stop using hard-coded colors and sizes in my CSS components?▼

How do I set up CSS custom properties for a web design system?▼

Set up CSS custom properties for a web design system by defining color, typography, spacing, shadow, radius, and breakpoint tokens in your global stylesheet. This architecture creates a single source of truth that all UI components must reference for consistent styling.

How do I implement theme switching with CSS custom properties?▼

Implement theme switching with CSS custom properties by mandating theme changes via data attributes on the root element. This approach dynamically overrides token values without altering individual component styles, ensuring consistent visual updates across the application.

What is the best way to enforce consistent spacing and typography across UI components?▼

The best way to enforce consistent spacing and typography across UI components is to apply a standardized CSS design system. This prohibits hard-coded values and requires all components to reference predefined spacing and typography tokens for visual consistency.

Can I use !important in my component styles when applying a CSS design system?▼

You cannot use !important in component styles when applying this CSS design system. The enforcement rules strictly forbid !important except for third-party overrides, ensuring that all visual values remain manageable through the standardized custom property tokens.

Why does my frontend UI look visually inconsistent across different components?▼

Your frontend UI looks visually inconsistent because of fragmented hard-coded values. Implementing a CSS design system solves this by providing a single source of truth for all visual values, ensuring every component references the same color, spacing, and shadow tokens.
