tailwindcss-v4-styling

What problem does it solve?

TailwindCSS v4 theming often causes conflicts when custom tokens misuse reserved variable namespaces, leading to layout breakage and inconsistent utilities. This Skill provides a disciplined approach to theme configuration, variable naming, and utility usage to prevent these issues across projects, migrations, and UI component implementations.

Core Features & Use Cases

• Theme configuration validation via the @theme directive to ensure correct CSS-first customization.
• Reserved namespace guidelines that prevent accidental overlap with container sizing, color, and typography tokens.
• Single spacing base + container tokens strategy to maintain stable layout utilities while allowing expressive custom tokens.
• Build and validation checks to verify generated CSS matches expectations (max-w, p-, etc.) and overall styling integrity.
• Use Case: Set up TailwindCSS v4 in a new project, implement a consistent design system, and debug styling issues without breaking layouts.

Quick Start

Configure your project by defining a single --spacing base and dedicated --container-* tokens in an @theme block, then remove tailwind.config.js usage and verify the build outputs.
