I’m making a child theme of the standard WordPress theme “2023” because I need to include a short php function. I notice that the standard theme doesn’t have a Functions.php file? nor is there one in my created file theme? I created the child theme with a plugin. Why doesn’t it have a Functions.php file? Do I just create one for the child theme? And if so, what else should go in it apart from my function?
Only create and code
Twenty Twenty Three doesn’t use a functions.php file.
However, you can just create your own functions.php file in the child theme and everything should still work as expected.
