Getting Started With WordPress Theme Development
WordPress themes control how your site looks. They are made up of files, like PHP, CSS, and JavaScript. Each file has a job. The PHP files handle the structure. CSS styles the look. JavaScript adds fun features.
The main file is index.php. This is the heart of your theme. Another key file is style.css. It tells WordPress about your theme. Template files decide how different parts of your site look. All these files work together.
A simple theme can have just a few files. But more files give more options. Understanding these files is the first step in making your own theme.
