Drupal themes templates development

What is Drupal ?
Drupal is used to build web sites. It's a highly modular, open source web content management framework with an emphasis on collaboration. Drupal is designed to be customized, but customization is done by overriding the core or by adding modules, not by modifying the code in the core.
Drupal can be used to build an Internet portal; a personal, departmental, or corporate web site; an e-commerce site; a resource directory; an online newspaper; an image gallery; and an intranet
