Drupal themes are a collection of files that determine the visual styling for a website. Themes usually contain several PHP, CSS, and image files, and include the arrangement of blocks in various regions, different layouts on different pages, and the selection of colors, fonts, and graphics.

By default, Drupal includes several themes that you can use or modify, including Bartik, Garland, Seven, and Stark. You can also download a contributed theme from , or create your own theme from an existing theme or from scratch.

Drupal modules can also define functions that can be addressed by your website’s theme.
