SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a robust and scalable CSS architecture for Rails applications, ensuring maintainability, consistency, and ease of development without relying on external frameworks like Tailwind.

Core Features & Use Cases

  • Modern CSS Standards: Leverages CSS custom properties, @layer, light-dark(), and semantic design tokens.
  • Component-Based Styling: Encourages a clear file structure where components own their styles.
  • Dark Mode Support: Implements automatic dark mode switching using light-dark().
  • Design Tokens: Centralizes design decisions (colors, spacing, typography) for consistency.
  • Use Case: When refactoring an existing Rails application's stylesheets, organizing them into a component-based structure, defining a clear design token system, and ensuring dark mode compatibility.

Quick Start

Use the css-architecture skill to set up the recommended file structure and define initial design tokens in app/assets/stylesheets/_global.css.

FAQPage Schema
How do I structure CSS in a Rails application for maintainability and scalability?▼

To structure CSS in Rails for maintainability, organize styles into component-scoped files and use semantic design tokens. This approach leverages CSS custom properties and @layer for cascade control to ensure scalability.

What is the best way to implement dark mode in Rails without external frameworks?▼

The best way to implement dark mode in Rails without frameworks is using the native CSS light-dark() function. This method enables automatic theme switching based on user preferences while keeping your stylesheets self-contained.

How do CSS design tokens improve stylesheet consistency in Ruby on Rails?▼

CSS design tokens improve stylesheet consistency in Ruby on Rails by centralizing design decisions like colors, spacing, and typography into semantic variables. Defining these tokens in a global stylesheet ensures all component-scoped styles reference a single source of truth.

Does this CSS architecture approach require any external dependencies or frameworks like Tailwind?▼

This CSS architecture approach does not require external dependencies or frameworks like Tailwind. It relies entirely on modern native CSS standards including custom properties, @layer, and light-dark() to style Rails applications independently.

How do I control CSS cascade specificity when using component-scoped styles in Rails?▼

To control CSS cascade specificity with component-scoped styles in Rails, use the native @layer rule. This establishes a clear cascade order, preventing utility classes and component styles from conflicting unexpectedly.
