HTML & CSS Evolution: Key Proposals (2022-2025)

The provided text details several significant advancements in HTML and CSS capabilities between 2022 and 2025, largely driven by Blink (Chrome) team involvement and collaborative cross-browser standardization. Key new features include the Popover API for declarative UI elements, Declarative Shadow DOM (DSD) to improve Web Component server-side rendering, and the inert attribute for managing focus and accessibility. Additionally, the document discusses Custom States for styling custom elements based on internal logic and Scoped Custom Element Registries to prevent naming conflicts in complex Web Component architectures. While most features have achieved broad browser support and are part of Baseline 2023/2024, Scoped Custom Element Registries remains an experimental feature as of early 2025.
