Athor here :) I totally feel you, and that is what Houdini’s Custom Layout is going to be about: https://github.com/w3c/css-houdini-drafts/blob/2b730220b2f3c26ec67445d1f96765ebb855421a/css-layout-api/EXPLAINER.md https://github.com/w3c/css-houdini-drafts/blob/2b730220b2f3c... I want to write a blog post about constraing based layouts on the web specifically, but the TL;DR on why we don’t have it already: Standardization is hard. It’s especially hard to reach consensus when: * the runtime for a layout algorithm is hard to estimate * it can _fail_ (which is unprecedented in CSS) * a new syntax for constrains would have to be defined.
