WordPress child themes are really simple to make, but I’ve noticed most tutorials are more complicated then they need to be.
All you need are two files in a folder: style.css + functions.php
Template: twentyseventeen with the name of your parent theme (it will be the folder name):
If you notice the formatting / CSS isn’t working, check the path to your Parents CSS
You can include a theme image by adding an image with the name “screenshot.png” in the root folder.
If you are lazy like me, here are the downloadable files.
Lastly, don’t forget to activate your new child theme.
