Eliminate JavaScript Forced Reflows

Medium Impact+8 points estimated

Why It Matters

31.83ms of forced reflow time blocks the main thread and degrades interaction responsiveness.

How to Fix

Audit your Elementor widgets and carousel JavaScript for DOM queries after style changes. Batch DOM reads/writes together using requestAnimationFrame. Consider replacing heavy carousel libraries with CSS-only solutions or lighter alternatives like Splide.js.

AI Performance Analysis

This WordPress site has concerning performance issues with a score of 79/100, primarily due to severe layout stability problems. The biggest issue is a massive layout shift (CLS score of 0.462) caused by content in the promotional steps section that moves around as the page loads, creating a jarring user experience. Additionally, the site has forced reflows that waste 32ms of processing time and multiple images without proper dimensions that contribute to the layout shifting. To significantly improve performance and user experience, the site needs to add explicit width and height attributes to images, optimize image compression and sizing (which could save 35KB), and fix the JavaScript that's causing forced reflows.

Other Optimization Recommendations

Fix Critical Layout Shift Issues

High Impact+15 points estimated

Why It Matters:

A major layout shift (CLS score 0.462) in the promotional section severely impacts user experience and Core Web Vitals.

How to Fix:

Reserve space for the u2-promo-steps-section div by setting explicit min-height in CSS. Add skeleton loading states for dynamic content areas. Ensure all promotional images have defined dimensions before content loads.

Add Image Dimensions and Optimize

High Impact+12 points estimated

Why It Matters:

Missing width/height attributes on carousel and promotional images cause layout shifts and slow loading times.

How to Fix:

Add explicit width='412' height='412' attributes to all Swiper carousel images. Set dimensions for promotional step images (360x188). Use WordPress image optimization plugins like ShortPixel to reduce the 35KB of wasted bytes from oversized social media icons.
