Using blocks a brief overview

One of the cool things about Drupal is that we can control blocks of content from a UI. In our theme layout, we have the regions; these are what tells Drupal Hey I'm a place for content, so let me show in the UI. Regions allow us to place blocks of content inside it. We have various ways to create blocks.

In the previous versions of Drupal, we could only add block name, title, and content by default, this then had the ability to set certain settings on how it would display.
