Child Theme – Default style.css or enqueue my_custom.css

Hi,

I already have a style.css file in my child theme folder to add CSS to. This works well.

But I saw this in your documentation:
Enqueue custom CSS
Assuming you have installed the child theme, which is always recommended for any custom modifications. We will enqueue a custom CSS file called my_custom.css
Steps to add a custom CSS file.
1. Create your custom.css file.
2.Create a new folder called “css” in child theme root directory and place your “my_custom.css” file in wp-content > themes > enfold-child > css > my_custom.css
3. Add the below code to your functions.php file…

What’s the difference between using the style.css file in my child theme folder which was already there or making a /css folder and putting my_custom.css file in there and enqueuing it with PHP?

Thanks.
