Not particularly anti-css, but you may be interested in concepts like size groups, properly predictable size-request-allocate cycle, width-for-height, constraint- and align-based layouts and in generally cleaning up the mess of non-orthogonally connected ideas in css. More explicitness and separation for properties. Remove bs like negative margins, make all distances multi-level, e.g. padding = max(el.paddings[]). Make bounding boxes explicit, make borders proper elements, etc. Boxing isn’t a bad model, CSS is just an awful implementation of it. Absolutely ridden with fragile incantations and absurd limitations which bring more issues and “solutions” that will break 99% of the times you touch it.
