Eliminate Render-Blocking CSS Resources
High Impact+25 points estimated
Why It Matters
Critical CSS files are blocking page render for 1,470ms and delaying First Contentful Paint significantly.
How to Fix
Inline critical CSS for above-the-fold content directly in the HTML head. Defer non-critical CSS files using media='print' onload='this.media="all"' technique. Split your main CSS bundle (acsall_v2.css) to separate critical vs non-critical styles. Consider using tools like Critical or Penthouse to extract critical CSS automatically.

AI Performance Analysis
This website has poor performance with a score of 70/100, primarily due to excessive unused code and slow loading times. The biggest issue is render-blocking CSS files that delay the First Contentful Paint by 1.47 seconds, while unused CSS (70 KiB) and JavaScript (699 KiB) are bloating page load times. The site takes 7.5 seconds to visually populate content and 14.2 seconds to become fully interactive, which severely impacts user experience. Removing unused code, optimizing CSS delivery, and implementing modern image formats could improve the score by 25+ points and dramatically reduce loading times.
Other Optimization Recommendations
Remove Unused CSS and JavaScript
High Impact+18 points estimatedWhy It Matters:
Over 700KB of unused JavaScript and 70KB of unused CSS are being downloaded unnecessarily, wasting bandwidth and slowing page load.
How to Fix:
Use webpack-bundle-analyzer or similar tools to identify unused code in your bundles. Remove unused Bootstrap components (currently 92% unused) and FontAwesome icons. Implement code splitting to load only necessary JavaScript per page. Consider replacing reCAPTCHA with a lighter alternative or load it only when needed.
Optimize Font Loading Strategy
Medium Impact+12 points estimatedWhy It Matters:
Custom fonts are causing 230ms delay in text rendering and contributing to layout shifts.
How to Fix:
Add font-display: swap to all @font-face declarations to show fallback text immediately. Preload critical fonts (FontAwesome, icomoon) using <link rel='preload' as='font'>. Consider using system fonts for body text and custom fonts only for headings to reduce font requests from 3 to 1.
