What is a block region?

A block region is a defined location on a content type. Regions are typically created as part of a site's overall theme and represent a structured section of the content type, however it ultimately is displayed.

Sidebars and Content

This section is where you will predominantly add your custom blocks. It's important to understand its default behavior. If you leave a region empty in this area, the other content will flow to fill it.

100% Content
Leave your sidebars for the page completely empty and your content will fill the defined space.

First Sidebar and Content
If your second sidebar is left empty, your content will flow to fill that space.

Content and Second Sidebar
If your first sidebar is left empty, your content will flow to fill that space, then leave room for the second sidebar.
