What to Know

How do developers build WordPress themes?

Building WordPress themes from square one requires a thorough understanding of several technical code features and best practices. Here's a breakdown of what's typically needed:

1. PHP
Template Files: You'll need to create various template files like index.php, header.php, footer.php, sidebar.php, single.php, page.php, archive.php, 404.php, etc. These define the structure of your pages.
WordPress Functions: Using WordPress's PHP functions for querying posts, accessing metadata, managing menus, etc. Examples include get_header(), wp_head(), get_template_part(), wp_nav_menu(), the_post(), the_content(), etc.
Custom Functions: Writing custom PHP functions in functions.php to hook into WordPress, manage theme options, enqueue scripts/styles, customize the admin area, or add theme support for features like post thumbnails, custom logos, etc.

2. HTML
Semantic Markup: Using HTML5 semantic elements for better SEO and accessibility (header, footer, nav, article, section, etc.).
Structure: Ensuring your theme's HTML structure is clean and logical, allowing for easy customization and understanding.

3. CSS
Styling: The style.css file is mandatory and should include the theme's metadata in its header. This file, along with additional CSS files, is used to style your theme.
Responsive Design: Media queries for different screen sizes to make your theme mobile-friendly.
CSS Preprocessors: Optionally, using tools like Sass or Less for more maintainable and modular CSS.

4. JavaScript
Interactivity: Add JavaScript for dynamic content, user interactions, or to enhance functionality (e.g., for menus, sliders, or custom admin panels).
Enqueue Scripts: Properly enqueue scripts in functions.php to load them on the front end or admin area without conflicts.

5. WordPress Theme Hooks
Actions and Filters: Leverage WordPress hooks to modify or extend the core functionality at specific points (e.g., wp_enqueue_scripts, after_setup_theme, widgets_init).

6. Template Hierarchy
Understanding and Utilizing: Know how WordPress selects which template file to use based on the content being requested (e.g., single post, specific category, author archive).

7. Custom Post Types and Taxonomies
Registration: If your theme requires custom content types or taxonomies, you'll need to register these in functions.php.

8. Theme Customization
Customizer Support: Integrate theme options into the WordPress Customizer using add_theme_support('customize-selective-refresh-widgets') and add_action('customize_register', 'your_customize_register_function') to allow real-time previews.

9. Widget Areas
Registration: Use register_sidebar() to define widget areas where users can add widgets.

10. Localization
Internationalization: Use functions like _e(), __(), esc_html_e(), to make your theme translatable. Create .pot files for translations.

11. Security
Sanitize and Escape: Always sanitize input data and escape output to prevent security vulnerabilities like XSS attacks.

12. Performance Optimization
Efficient Queries: Use WordPress's caching mechanisms or write efficient database queries.
Lazy Loading: Implement techniques for images or content to load only when necessary.

13. Accessibility
ARIA and HTML5: Ensure your theme follows accessibility standards, including proper use of ARIA labels, skip links, and semantic HTML.

14. Version Control
Git: While not part of the theme code, using version control during development helps manage changes and collaborate if needed.

15. Theme Metadata
In style.css: Include essential information like Theme Name, Theme URI, Author, Description, Version, License, etc., for WordPress to recognize your theme.

16. Documentation
Inline Comments: Good practice to comment your code for maintainability, especially in functions.php or complex template files.

When building from scratch, adhering to WordPress coding standards, ensuring compatibility with the latest WordPress versions, and testing across different browsers and devices are also crucial.

This framework allows for the creation of themes that are not only functional but also maintainable, scalable, and user-friendly.
