css

A complete, MDN-typed CSS engine for nimony / Nim 3.0 — parse a whole stylesheet, then validate every value against its official grammar, every function against its own signature, and every selector against Selectors-4. Pure logic, standard library only, no dependencies.

import css

validateValue("width", "clamp(1rem, 2vw, 3rem)").valid   # true
validateValue("width", "clamp(1rem, 2vw)").error         # "clamp() expects 3 arguments, got 2"
validateSelector("ul > li:nth-child(2n+1)").valid        # true

Driven entirely by the MDN data in css/data/*.json — track a spec change by dropping in fresh JSON. Successor to the Nim-2 thing-king/css.
