Remove some parts of URl with .htaccess? – Apache

I’m developing a website and trying to obtain:

http://localhost/dir1/dir2/index.html#home

to become:

http://localhost/index.html#home

Tried:

RewriteEngine On
RewriteRule ^/?$ /dir1/dir2/

but no luck, it redirects to http://localhost/dir1/!

My index.html file is under /var/www/html/dir1/dir2 folder, as you imagine see from the URL.

Any help please?

Thanks

*Edit**:

The .htaccess is placed in the root folder, so in dir1‘s parent.
