A WICG proposal and living explainer for rendering HTML content into 2D and 3D <canvas> elements, introducing primitives like the layoutsubtree attribute and drawElementImage(). It is implemented behind a flag in Chromium and continuously updated based on community feedback.

Use cases

• render styled laid-out text and HTML content inside a canvas
• improve accessibility of canvas-based content
• apply WebGL shaders as effects to HTML elements
• render rich 2D HTML content onto surfaces in a 3D scene
• export HTML content as images or video
• build chart legends and in-game menus with canvas

When to choose

• you are a browser vendor or spec author evaluating canvas HTML rendering APIs
• you want to follow or give feedback on the HTML-in-Canvas proposal
• you are prototyping canvas rendering features behind the Chromium flag

When to avoid

• you need a production-ready API today, since it is flag-gated and not standardized
• you want a library or framework rather than a specification document
• your project must support browsers without this experimental feature
