There are two great methods to add custom functions to your site without customizing parent theme:
Adding them via Child Theme‘s functions.php file or Create a custom functions plugin
In this post I’m showing you the second one, how to create a custom functions plugin in WordPress.
What is child theme?
A child theme in WordPress allows you to change the functionality of a theme without having to customize the original/parent theme’s template files. Since the child theme is stored separately, you don’t need to redo the changes next time you update a theme.
If the automatic paragraph seems annoying to you, you can disable or remove it from the content or excerpt view from a WordPress site.
