This document provides an overview and comparison of different page building tools in Drupal: blocks, Context module, and Panels module. Blocks allow placing content into regions defined by a theme, while Context and Panels provide more powerful and flexible options. Context allows managing conditions and reactions for site portions, and Panels provides a drag-and-drop page builder that places content visually into layouts. Both tools are more powerful than blocks, with Panels generally being more suitable for complex or variant page layouts and Context better for developer-driven or region-based sites.
