Creating a child theme in WordPress
This is a no-nonsense instruction of how to create a child theme in WordPress. We create it from the existing theme “twentynineteen”
1. Create a folder, name it “twentynineteen-child”.
2. Create a new file style.css
3. Add this to the file. Later you will add your customised CSS styles here.
4. Add a new file “functions.php” in the same folder with this content. Later you will add your customised features here.
5. Last, create an empty index.php.
6. Upload your theme to your site. Easiest is to ZIP the directory like this:
zip get.zip twenty nineteen-child/*
