High Impact+12 points estimated
Why It Matters
97% of Bootstrap CSS and 66% of jQuery are unused, wasting 285KB of network resources.
How to Fix
Replace full Bootstrap with only needed components or use a CSS framework like Tailwind with purging. Remove unused jQuery features by using a custom build or replace with vanilla JavaScript. Use tools like PurgeCSS to eliminate unused CSS rules automatically.

AI Performance Analysis
This website has poor performance with a score of 75/100, primarily due to slow loading times that hurt user experience. The biggest problem is render-blocking resources, especially a large Bootstrap CSS file that's delaying page rendering by over 2 seconds, causing your First Contentful Paint to reach 3.2 seconds and Largest Contentful Paint to hit 4.5 seconds. The site is also bloated with unused code - 97% of the Bootstrap CSS and significant portions of jQuery aren't being used, wasting 158KB of CSS and 124KB of JavaScript that users have to download unnecessarily. Addressing these render-blocking resources and removing unused code could dramatically improve your Core Web Vitals and potentially boost your performance score by 20+ points.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+15 points estimatedWhy It Matters:
Bootstrap CSS and jQuery are blocking page render, delaying LCP by 2.35 seconds.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Load non-critical CSS asynchronously using media='print' onload='this.media="all"'. Defer jQuery and JavaScript execution using async/defer attributes or move to footer.
Add Explicit Image Dimensions
Medium Impact+8 points estimatedWhy It Matters:
Images without width/height attributes cause layout shifts that hurt user experience and CLS.
How to Fix:
Add width and height attributes to all img elements, especially dual1.avif and dual2.avif banner images. Use CSS aspect-ratio property for responsive images while maintaining dimensions. Reserve layout space before images load to prevent content jumping.
