About the Book
Modern WordPress theme development is about much more than changing colors and creating page templates. Building WordPress Themes From the Root Up teaches developers how to create professional themes that provide strong design systems while remaining fast, accessible, maintainable, flexible, and compatible with the larger WordPress ecosystem.
Readers explore modern block-theme architecture, theme.json, templates, template parts, patterns, style variations, responsive layouts, CSS strategy, typography, navigation, accessibility, performance, internationalization, child themes, WooCommerce compatibility, and testing.
The book also explains one of the most important principles of professional WordPress development: understanding the difference between presentation that belongs in a theme and persistent functionality that belongs in a plugin. Later chapters explore starter-site systems, commercial theme development, licensing, updates, documentation, customer support, and building themes that can serve multiple real-world business websites without becoming unnecessarily complicated.
