Could you build this?
No Creating a Turing-complete computing system purely in CSS is an esoteric theoretical hack involving advanced selectors, recursive layout tricks, and state encoding without executing any JavaScript.
What it would actually take: The architecture relies on cleverly chained CSS pseudo-classes (:checked, :focus, :has, @container) and CSS custom properties (variables) to maintain memory state across HTML elements. The hard part is constructing universal logic gates (NAND/NOR) and clock cycles purely through DOM reflows and CSS specificity hierarchies. This requires academic-level understanding of formal automata theory and CSS parsing/evaluation internals.
