Why It Matters
JavaScript is causing 1.87 seconds of forced reflows, blocking the main thread and preventing user interactions.
How to Fix
Audit your Elementor custom code and jQuery scripts causing layout thrashing. Batch DOM reads before writes, cache geometric properties like offsetWidth, and avoid reading layout properties after DOM changes. Consider replacing heavy Elementor animations with CSS-based alternatives.

AI Performance Analysis
This WordPress site has severe performance issues with a critically low score of 38/100. The biggest problem is excessive JavaScript execution time (2.8 seconds) combined with forced reflows that are blocking the main thread and causing a painfully slow Largest Contentful Paint of 9.9 seconds. The site is loading 277 KiB of unused JavaScript from Google Analytics/Tag Manager and has 26 KiB of unused CSS, while WordPress plugins like Elementor and WooCommerce are causing significant layout thrashing. Reducing JavaScript payloads, minifying code, and optimizing the heavy plugin usage could potentially improve the score by 40+ points and dramatically enhance user experience.
