A child theme is a sub-theme that inherits the look, feel, and functions of the parent theme. When you make modifications to the child theme, they are kept separate from the parent theme's files.
With this child theme you can add basic or advance Custom Post Types as the required code for them is written in relative file functions.php, also you can add those as many as you want by copying & pasting the code multiple times & change the name & attributes according to your Custom Post Type liking.
To make it your's Child Theme you need a just little bit changes in style.css
- Make a folder with you parent theme name with adding "-child" in my case twentytwentythree (parent theme folder name) twentytwentythree-child (child theme folder name) & paste these files into child folder.
- Go to style.css change the theme name to the theme you're working on at the top of the comment.
- Change the template to the theme folder name you want to make this a Child Theme, in my case its twentytwentythree.
- Activate it & have fun with it.
- Make sure to after you activate the child theme go to settings -> permalinks go at the bottom & hit save changes, your Custom Post Types will be shown. otherwise you'll see 404 Error, also you just only need to do it once.
- Currently in development.
Added the both Custom Post Type Page Layouts in current build (FSE Standard), next I'm going to import Global Styles (Browse Styles) from the parent theme.
