Working with Regions
Most of the content found on Drupal pages is output inside a region. Typical regions include the header, footer, sidebars, and content (see Figure 15–8); these regions often play a large part in defining the high-level structure of your HTML markup. An option appears in the blocks interface at
admin/structure/block for each region, allowing site administrators to control and position the blocks inside them.
Themes have full control over defining and determining the placement of printing and styling regions. An example of what this looks like in the Bartik theme is shown in Figure 15–9.
