css-cascade-layers

What problem does it solve?

CSS cascade and specificity wars create unpredictable styling in large codebases. Cascade layers provide explicit priority control to keep resets, defaults, components, and utilities in a predictable order.

Core Features & Use Cases

• Explicit layer declarations: Define named layers to order CSS by purpose (reset, defaults, components, utilities).
• Controlled overrides: Use @layer and @import layer(...) to pin third-party styles and avoid !important hacks.
• Architectural patterns: Align with ITCSS-inspired structures for scalable design systems and multi-team projects.
• Real-world scenarios: Managing design tokens, theme variations, and component libraries in large apps.

Quick Start

Set up a full layer stack at the top of your main stylesheet and add a simple example demonstrating how higher layers win over lower layers.
