Template Hierarchy

The WordPress template hierarchy is a system that determines which template file is used to display different types of content on a website. It’s essential to understand the template hierarchy when developing a custom WordPress theme. The hierarchy starts with the index.php file, which is the default template file used for all pages. From there, WordPress looks for more specific template files based on the type of content being displayed, such as single.php for individual posts and page.php for individual pages.

Custom Theme Development

Developing a custom WordPress theme allows for greater control over the site’s design and functionality. Custom themes can be created from scratch or built upon an existing theme. When developing a custom theme, it’s important to follow best practices and ensure the code is well-organized and easy to maintain.

Child Themes and Parent Themes

A child theme is a theme that inherits the functionality and styling of a parent theme. Child themes are useful when making modifications to an existing theme, as they allow for customization without affecting the original theme’s code. When creating a child theme, it’s important to ensure that the parent theme is well-written and follows best practices.

Theme Customizer API

The Theme Customizer API allows users to customize the appearance of their site in real-time. It provides a user-friendly interface for modifying the site’s colors, fonts, and other design elements. Theme developers can add custom settings to the Theme Customizer API to allow users to customize their theme further.
