Hi Stefano,
Thanks for contacting Syncfusion support.
We suggest you to download the script and style codes from the cdn link itself.
Or else you can also fetch the scripts and styles from your installed Syncfusion build. Click on the “Explore Demo Source” button. It will open a folder, in that under the “wwwroot” folder you can get the styles and scripts for that particular version. Please refer the screenshot below,
Please get back to us if you need further assistance.
Regards,
Renjith Singh Rajendran.
