taffy

If you don't need JavaScript, then you might be interested in https://github.com/DioxusLabs/blitz. It pulls in Servo/Firefox's CSS engine Stylo (and Servo's HTML parser html5ever) and pairs it with our own layout engine (which we are implementing mostly as libraries: Taffy [0] for box-level layout and Parley [1] for text/inline layout) and DOM implementation. Rendering and networking are abstracted behind traits (with default implementations available) and you can drive it using your own event loop. Minimal binary sizes are around 5mb (although more typical build would be more like 10-15mb). [0]: https://github.com/DioxusLabs/taffy [1]: https://github.com/linebender/parley

> The current roadmap lists Shadow DOM and CSS Grid as priorities I've been working on the CSS Grid support. About to land "named grid lines and areas" support which should make a bunch more websites layout correctly. I'm biased because it's my project, but IMO the approach Servo is using for CSS Grid is pretty cool in that the actual implementation is in an external library (Taffy [0]) that can be used standalone and is widely used accross the Rust UI ecosystem, including in the Blitz [1] web engine (which also uses Taffy for Flexbox and Block layout), the Zed [2] text editor, and the Bevy [3] game engine. I'm hopeful that this approach of breaking down a web engine into independently usable modules with public APIs (which builds upon Servo's earlier work on modular libraries such as Stylo and html5ever) will make it easier for people to
