Drupal separates content and presentation through themes. These themes control the visual look and feel of your site, allowing customization of layouts, colors, fonts, and more. You can build a theme from scratch or extend existing ones (sub-themes) for a solid foundation. The Twig templating engine lets you dynamically insert content into your theme's structure, ensuring a cohesive user experience.

Click "Install" and then "Enable" to activate the theme.

Most themes offer basic configuration options. Explore the "Appearance" section in Drupal to find theme-specific settings.

Drupal's modular architecture empowers customization through reusable components.

These modules extend core functionality, adding features like user management, content creation, e-commerce, and more. You can combine and configure modules to tailor Drupal to your specific needs, creating complex websites without reinventing the wheel. This flexibility promotes efficient development and maintainability.
