WordPress Theme Handbook vs Theme Developer Handbook

 

WordPress Theme Handbook vs Theme Developer Handbook

Both are official WordPress documentation, but you can think of them as one large learning resource organized around different aspects of theme development.

1. WordPress Theme Handbook

The is the main documentation for learning how WordPress themes work.

It covers topics such as:

• Theme structure

• Template files

• The WordPress Loop

• Template hierarchy

• functions.php

• CSS and JavaScript

• Theme features

• Navigation menus

• Featured images

• Custom templates

• Block themes

• Classic themes

• Theme development best practices

For a beginner, I recommend learning in this order:

Theme Basics
     ↓
Theme Structure
     ↓
style.css
     ↓
index.php
     ↓
header.php / footer.php
     ↓
functions.php
     ↓
The Loop
     ↓

     ↓

2. WordPress Theme Developer Handbook

The is essentially the developer-focused documentation within the WordPress theme documentation.

It goes deeper into how to actually build and develop themes, including the technical APIs and standards you'll use when creating professional themes.

For example:

<?php

function my_theme_setup() {

    add_theme_support('post-thumbnails');

    register_nav_menus(
        array(
            'primary' => 'Primary Menu'
        )
    );
}

add_action('after_setup_theme', 'my_theme_setup');

You can use the documentation to understand what add_theme_support(), register_nav_menus(), and add_action() actually do.

Which one should you use?

If you're learning WordPress theme development from the beginning, follow this path:

Step 1: Learn the basic concepts in the Theme Handbook.

Step 2: Build a small classic theme like the demo we created above.

Step 3: Learn the Template Hierarchy.

Step 4: Learn WordPress functions and hooks.

Step 5: Learn theme security and coding standards.

Step 6: Move into block themes and Full Site Editing.

Step 7: Build a complete professional theme.
