I’m excited to share a new project from Adobe Spectrum Web Eng that tracks support for #CSS features within and across the shadow DOM. Think “CanIUse” but for CSS for web components.
The goal is to surface how modern CSS behaves when light and shadow DOM contexts meet, providing visibility into feature parity, usage details, and outstanding issues and bugs. We hope it’s a useful resource for the web components community, and we’d love your feedback and contributions!
