Get a different design on the single.php page

Hi everyone,

I have a question about the page single.php where I list all my post.

I currently have 2 categories on the same WordPress.

1 is for hunting and the second is for the sports.

I would like to give a different “theme css” for each categories when I list them and when I read a specific one.

I’m not sure if we can do something like the get_header(); where we can add $string in the () to call a different header.

If you don’t understand or you want me to leave more information about my request, please let me know.

Thx
