This is awesome. I've always wanted to know how the actual layout portion works (or at least, can work in a simple way). I think these kinds of resources are really valuable and people should be empowered to make bespoke-ish web renderers as the need arises.

Author here. Layout is my favorite part of the browser—my dissertation is largely about formalizing browser layout—and so far the book only covers the basics, like the layout tree and how layout is computed with multiple tree traversals, but even understanding those basics I think gives you a huge advantage when thinking about web page layout tasks.
