As you can see there are required just 2 files. Index.html – like default template and style.css where should theme data like description and name.

Also, there are optional files:

  • functions.php: loads right after the theme is initialized and in case you need to add your custom function. Extend extra elements and hooks in the functions. php file.
  • theme.json: here you can configure theme styles and settings which will be integrated with the user interface.

Standard folders:

WordPress can have a many more folders than provided on the screenshot but there is list of standard folders:

  • parts: here can be stored template parts for your theme (e.g. header, footer, sidebar)
  • patterns: reusable patterns. There is no need to register them separately, it’s enough to put them into this folder.
  • styles: variations of theme stylings.
  • templates: document structure for the front end.

When we talking about classic theme structure, there are also 2 required files: style.css and index.php. But template hierarchy a bit different:

To read this image need from right to left. By default you have index.php template which will be applied to all the posts, pages, home and archive.

So if you need to create separate template for the front page you can create home.php which will be applied to home and blog archive page. And if you need separate templates for both need to create one more template file front-page.php. In this case we have home.php for the blog page and front-page.php for the Landing page.
