How to build a site hierarchy in html?

Question

htaccess

In .htaccess I remove the name of the folders

RewriteCond %{DOCUMENT_ROOT}/pages/$1 -f
RewriteRule ^(.*)$ pages/$1 [L,QSA]

The page https://example.com/priceis in the pages folder. Further from this page we go to https://example.com/Anticellyulitnyi_massaj.
How to make the address written not https://example.com/Anticellyulitnyi_massaj, but https://example.com/price/Anticellyulitnyi_massaj?
