Over the course of the next several months, we’ll be migrating the underlying technical implementation of Docs from the current HTML-based rendering approach to a canvas-based approach to improve performance and improve consistency in how content appears across different platforms. This article talks about some of the tradeoffs between Canvas and DOM approaches: https://www.kirupa.com/html5/dom_vs_canvas.htm https://www.kirupa.com/html5/dom_vs_canvas.htm The thing that seems least appealing about replacing DOM rendering with Canvas rendering is the lack of CSS. You may gain performance, but assuming even a fraction of the responsibilities CSS handles so well seems very daunting. That's why I suspect this approach will do best where the content least resembles a read-only document, and more resembles a game, such as Google Docs.
