Progressive Enhancement
Purpose
Prefer CSS solutions over JavaScript. "The best code is no code."
Quick Decision
Before writing JS, ask:
- "Can CSS solve this?" → Grid, Flexbox, :has(), transforms
- "Is this needed now?" (YAGNI) → No evidence = don't implement
- "Simplest solution?" (Occam's Razor) → 3 lines CSS > 50 lines JS
