Preparing Your WordPress Theme
WordPress themes have a basic structure. The main files are style.css, index.php, and functions.php. Each file has its own job. The style.css is for design. The index.php is for layout. The functions.php is for special features. These files work together to make your site look good.
A child theme is a safe way to change your site. It keeps your changes safe when you update your main theme. First, make a new folder. Name it after the main theme with “-child”. Next, make a style.css file. Add a few lines of code to link it to the main theme. Now, you can add or change code without worry.

Organizing Script Files
