The name of the theme is needed

Welcome. Does anyone know what theme I have to use to achieve the effect that is on this page? Or maybe someone knows the name of this theme. Thank you in advance

Hello,

I hope you are doing well today.

That theme is not available for us to see but you can try using one of our free themes:

https://colorlib.com/wp/themes/

Our Sparkling and Blaskan themes seem similar to that website.

Best Regards,
