If you’ve used WordPress to publish posts or tweak a theme, you’re already halfway to development. WordPress development means creating themes, plugins, and custom solutions that extend what a site can do—without hacking core files.
What You Need to Know
– PHP powers WordPress logic.
– HTML structures your pages.
– CSS styles your pages.
– JavaScript adds interactivity (Gutenberg blocks use React under the hood).
Local Development Setup (Pick One)
– Local WP (by WP Engine) – Very beginner-friendly.
– DevKinsta – Quick PHP/MySQL/NGINX stack.
– XAMPP/MAMP – Manual but flexible.
– Docker – Advanced, reproducible environments.
Where Your Code Lives
– Themes control presentation.
– Plugins control functionality.
– Use a Child Theme to customize an existing theme safely.
Typical WordPress Installation Structure (Simplified)
wordpress/
├─ wp-admin/
├─ wp-content/
│ ├─ plugins/
│ └─ themes/
│ ├─ twentytwentytwo/
│ └─ your-child-theme/
└─ wp-includes/Safest Rule
Never edit files in wp-core (wp-admin, wp-includes). Work inside your theme or, better, your own plugin when adding functionality.
