Sometimes I come across constructions like "site's header" or "site's navigation", but as I know the possessive case in most cases shouldn't be used with inanimate nouns. So my question is – are those correct collocations and might they be used in some more formal contexts?
are correct and refer to either the site's top/beginning or possibly some picks used to move through the site.
Using possessives with inanimate nouns often happens
The bike's tires need air.
The teddy bear's fur is wet.
The site's header is an ugly color.
The site's navigation is not intuitive.
