How to Use Asynchronous Loading for custom CSS and JavaScript with Webflow
Using asynchronous loading for custom CSS and JavaScript is crucial for improving your website’s loading speed and overall performance. Asynchronous loading allows these resources to load in the background without blocking the rendering of the page, ensuring that the content is visible to users as quickly as possible.
How to do it on Webflow?
Implement the async or defer attributes in your <script> tags for JavaScript, and consider loading non-critical CSS asynchronously using techniques like media attributes or preload.
Do's
✅ Adding the async attribute to your JavaScript like this:
<script src="custom.js" async></script>
This allows the script to load in the background while the page content continues to render, improving the initial page load time.
Don'ts
❌ <script src="custom.js"></script>
This can significantly delay the time it takes for your page to become visible and usable to users, leading to a poor user experience and potentially higher bounce rates.
