If you want to create a different category template of wordpress theme to display specific category. You can do this by saving your Category template as category-xxx.php . Please note that adding hyphen (“-“) and the category id to the file name.
So, category-xxx.php will be used to display category that have ID xxx, & category-1.php will be used for category ID 1.
You can follow the same logic of hyphen and id number for individual post template creation.
Very nice post. I certainly appreciate this website.
