Incorrect CSS/JS order causes render-blocking delays and FOUC—users see unstyled content while waiting for styles to load.
Quick Reference
- Load all CSS files before JavaScript in the document head
- Use async/defer for non-critical JavaScript
- Inline critical CSS for faster first paint
- Prevents FOUC (Flash of Unstyled Content)

Fix
