X86CSS – An x86 CPU emulator written in CSS

AI Analysis
●●●●GemWizardryZero to OneRabbit Hole
Emulating x86 in pure CSS. No JavaScript. It actually works and runs C programs.
Strengths
- •Genuine constraint-based wizardry: x86 instruction set in CSS selectors and animation timing—no precedent
- •Zero user input required (unlike prior CSS CPU hacks): animation + container queries = true autonomy
- •Fully documented approach: author committed to blog post explanation, GitHub transparent
Weaknesses
- •Not practical (author admits)—real-world use is nonexistent
- •Performance is glacially slow by design—CSS animation clock makes it deliberately inefficient
