Fix Forced Reflow Issues
Medium Impact+5 points estimated
Why It Matters
JavaScript is causing 95ms of forced reflows, blocking the main thread and degrading INP.
How to Fix
Batch DOM reads and writes to avoid layout thrashing in React components. Use useLayoutEffect instead of useEffect for DOM measurements. Cache geometric properties like offsetWidth instead of repeatedly querying them in your Next.js components.

AI Performance Analysis
This Next.js/React website has decent performance with a score of 80/100, but suffers from a critically slow Largest Contentful Paint of 4.9 seconds, which far exceeds Google's recommended 2.5 seconds. The biggest issue is render-blocking CSS files that are delaying the initial page render by 440ms, preventing users from seeing content quickly. The site is also loading 27KB of unused JavaScript and using outdated polyfills that aren't needed for modern browsers, adding unnecessary bloat. Addressing the render-blocking stylesheets by inlining critical CSS and removing unused JavaScript could significantly improve load times and boost the performance score into the 90s.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+12 points estimatedWhy It Matters:
Critical CSS files are blocking initial render and delaying LCP by 450ms.
How to Fix:
In Next.js, inline critical CSS using styled-jsx or CSS-in-JS for above-the-fold content. Move non-critical CSS (36d3ad196d96d2e6.css) to load after first paint using dynamic imports. Use Next.js font optimization to prevent FOIT with custom fonts.
Remove Unused JavaScript Code
High Impact+8 points estimatedWhy It Matters:
76% of JavaScript in main chunk (27KB) is unused, creating unnecessary network overhead.
How to Fix:
Enable Next.js bundle analyzer to identify unused code in chunks/1143-0ab9339f79187463.js. Implement dynamic imports for components not needed on initial load. Use Next.js tree shaking by ensuring named imports instead of default imports from libraries.
