You-dont-need-javascript is a reference collection demonstrating CSS-based implementations of interactive UI components typically built with JavaScript.
The project addresses the assumption that JavaScript is necessary for interactive web features by showcasing pure CSS solutions for common patterns like accordions, carousels, popovers, tooltips, and menus. It works by providing working examples of these components built entirely with CSS, proving that many interactions can be achieved without JavaScript dependencies. This approach reduces page complexity, improves performance by eliminating script overhead, and decreases the surface area for bugs and security issues.
Developers should consider this collection when building lightweight projects, progressive enhancement layers, or when exploring CSS capabilities they may not have fully utilized. It suits projects where minimizing JavaScript is a priority, whether for performance reasons, accessibility concerns, or architectural preferences. The repository functions as both a learning resource and a practical reference for developers who want to understand what CSS alone can accomplish before reaching for JavaScript solutions.
The project maintains a curated collection of examples with active community contributions adding new component implementations and improving existing ones. The repository accepts pull requests for additional CSS-based patterns and refinements to current examples. Documentation is kept current with working demonstrations of each technique, allowing developers to see implementations in action rather than reading theoretical descriptions.
