What strategies can I use to reduce the impact of render-blocking resources when using Bootstrap?

Your page's first paint is being blocked by resources. To improve loading speed, try delivering critical JS/CSS inline and deferring non-critical assets.

css/custom-styles.css css/homepage.css

I recently ran tests on GTmetrix and PageSpeed Insights and received this message about my website's loading speed issue. It's impacting the performance of my site. Can someone offer guidance on resolving this? Appreciate any assistance, Thanks.

Optimize your website's performance by delivering critical CSS separately and deferring non-critical CSS:

For critical CSS, extract the necessary class definitions and place them within a <style> block in the head of the page:

<style type="text/css">
.accordion-btn {background-color: #ADD8E6;color: #444;cursor: pointer;padding: 18px;width: 100%;border: none;text-align: left;outline: none;font-size: 15px;transition: 0.4s;}.container {padding: 0 18px;display: none;background-color: white;overflow: hidden;}
</style>

Non-critical CSS can be deferred for faster load times:

<link rel="preload" href="styles.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
<noscript><link rel="stylesheet" href="styles.css"></noscript>
