How can I ensure compatibility with the latest version of jQuery in newly published Webflow sites?

Webflow automatically includes jQuery 3.6.0, but if you need to ensure compatibility with a newer version, follow these steps.

1. Check Webflow’s Built-in jQuery Version

• Webflow includes jQuery 3.6.0 as of recent updates.
• If your code requires a newer version, you must manually override the default jQuery.

2. Load a Newer jQuery Version Manually

• Remove Webflow’s default jQuery to prevent conflicts:

1. Open Project Settings > Custom Code.
2. In the Footer Code section, add:
   ```html ')```
3. Replace 3.x.x with the latest jQuery version number from jQuery’s official CDN.

3. Test Existing jQuery Functions

• Ensure any custom scripts using jQuery still function correctly.
• Use the browser console (F12 > Console) to check for errors or deprecated functions.

4. Verify Webflow Interactions Compatibility

• Some Webflow interactions rely on jQuery.
• If interactions break, use Webflow’s default version or test compatibility with .noConflict() mode:
  ```html```

5. Publish & Test

• Publish your site and check functionality on multiple browsers.
• Open the browser console to confirm no compatibility errors appear.

Summary

Webflow uses jQuery 3.6.0, but you can override it by adding a custom script in the footer. Ensure your custom code and Webflow interactions remain functional after switching jQuery versions. Always test your site thoroughly after making changes.
