I want to know how to fix the browser address bar value.

Hello!

I'm creating a site.

The main.html is a situation where only the data inside is different depending on the id value after ?.

There is index.html at the beginning.

With url visible only as index.html/a

I want to pass main.html?id=a.

First of all, the way I forced myself to think is

Create a folder called a on the same path as index.html, and create index.html in it

index I thought ... how to make it. / just blown away, and a html

This is a crazy way to get too much data.ㅠ<

I don't even know what to search for keywords, so I'm posting a question here.

Readers, if you have any good ideas or methods, please help!
