WordPress manages content. Themes control how that content looks.
What is a WordPress Theme?
A WordPress theme controls the layout, design, typography, and structure of your website. WordPress itself is just a content management system (CMS). The theme decides how posts, pages, and archives are displayed.
WordPress Core vs Theme vs Plugin
| Component | Purpose | Example |
|---|---|---|
| WordPress Core | Main system files | wp-admin, wp-includes |
| Theme | Controls layout & design | style.css, index.php |
| Plugin | Adds extra functionality | SEO, Forms, Security |
Where Are WordPress Themes Located?
All themes are located inside:
wp-content/themes/Each theme has its own folder inside this directory.
