Understanding the Structure of Your Theme

When creating a WordPress theme, it’s helpful to visualize its structure as a blueprint of a house. Here’s how:

  • Header (header.php): The entryway of your house that greets visitors.
  • Footer (footer.php): The foundation that supports the entire structure.
  • Content (content.php): The rooms where all the activity happens.
  • Sidebar (sidebar.php): The hallway that provides additional navigation options.
  • Single Post (single.php): The living room, showcasing individual stories.
  • Page (page.php): The various rooms for different purposes.
  • Index (index.html): The overall layout of your home.
  • Comments (comments.php): The discussions taking place around the dinner table.
  • Functions (functions.php): The plumbing that makes everything work smoothly.

The Loop is where WordPress fetches and displays your content. Think of it as the conveyor belt in a factory, bringing in posts, pages, comments, and custom post types in an organized manner to keep your production line (website) running efficiently.
