Order CSS files correctly

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)

Check

Verify that all CSS files are loaded before JavaScript files in the document head to prevent render-blocking and ensure proper styling precedence.

Fix

Reorganize head section to load all CSS files before JavaScript files, except for asynchronous scripts that don't block rendering.

Explain

Explain why CSS should load before JavaScript to prevent FOUC (Flash of Unstyled Content) and ensure optimal rendering performance.

Code Review
