Native Web Components Skill

What is it?

A skill for building framework-free web components using only native HTML, CSS, and modern browser platform features. It prioritizes Declarative Shadow DOM (DSD), CSS-first interactivity, and the newest baseline features (2025 → 2024 → 2023) to ensure compatibility across the latest four stable browser versions.

Why use it?

• Zero dependencies: No frameworks, bundlers, or build tools required
• Maximum performance: Native platform features are faster than JavaScript alternatives
• Cross-browser stability: Baseline features ensure support across Chrome, Edge, Firefox, Safari
• Future-proof: Uses the newest standards with graceful degradation
• Minimal JavaScript: CSS handles interactivity; JS only for progressive enhancement
