Blink's Web Feature Prototyping: HTML & CSS

from Blink286 Hosted by Free Debreuil

The provided text describes the structured process for adding new HTML and CSS features to Blink, Chrome's rendering engine. It details the multi-stage workflow, starting from incubation with explainer documents and early feedback, through prototyping the feature behind a runtime flag in C++ code. The explanation then covers implementing both HTML and CSS features, including defining Web IDL interfaces for HTML or updating CSS property definitions in JSON5, and ultimately, ensuring robust platform testing using Web Platform Tests (WPT) to guarantee interoperability and prevent regressions. This methodical approach ensures that new web features are carefully developed, tested, and aligned with web standards before being shipped to users.
