How to access a website located on a computer through a smartphone browser?

Question

Browsers

There is a folder with site files on the computer, if you open index.html, then the site will naturally open without the Internet, I need to open the site from this folder, which will be on the computer on the smartphone, how to do this?
Is there a special, not complicated program for simulating a server that connects to your wi-fi point and transmits a fictitious site address to connect to a folder in order to open the site in a browser on a smartphone?
Just don't ask why

Answer 1

Network share via smb or server. And the server is better than reaching out from the phone via samba.
But why, if you can put a server?
