creating a child theme and modifying ie. header.php Hi

creating a child theme and modifying ie. header.php

Hi dear,

I am just creating my first child theme. Please can you help me to understand better the following?

1. Style.css: I have created this new file in the child theme directory with only my part of customizing code part. Before I was adding this code to the “edit CSS” for my theme. Now I can copy those code in the child style.css? correct?

2. functions.php: created this file enqueueing the parent and child theme stylesheets only. Nothing else!

3. But what if I want to edit ie. the header.php?

I need to copy the full file from parent theme and add my customizing code or simply create a new empty file header.php in the child theme and add only my customizing code?

Thank you so much for your help.

Have a nice day.
