## What it is
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

## Facets
- artifact type: learning-resource
- maturity: experimental
- function: graphics, ui-components, accessibility, animation
- domain: web-development, frontend, graphics, browser-extensions
- platform: browser
