It may be a horizontal rectangle on the left or on the right of content or in the footer. Sidebars are very important in WordPress for display of content differing from the main posts. For example, a short list of the latest articles, the latest comments, a random menu of page list or post categories can be easily displayed across the whole site or on its specific pages.
