Who Should Read This Handbook?
The Theme Developer Handbook is a self-contained resource to help you learn the basics of WordPress theme development. You should read this handbook to accomplish a number of things:
- develop a child theme meant to work with a parent theme;
- create a new theme based on an existing one;
- understand the inner workings of themes in general; and
- develop a theme based on nothing but your imagination.
To get the most out of this handbook, you should have an understanding and some experience with web technologies, such as HTML, CSS, and PHP. You should also be comfortable with setting up and configuring websites using WordPress and the editor.
This handbook provides the basic information required to develop block themes or classic WordPress themes, including in-depth coverage of essential template tags and functions.
WordPress is a vast subject. Covering every possible tag, function, and scenario is beyond the scope of this handbook. If you need help with specific functions, you can find that information in the code reference.
The purpose of this handbook is to give you a solid foundation for WordPress theme development, to provide step-by-step instruction in building basic themes, and to provide tips and resources useful in furthering your skills.
