A typical blog has two columns that appear under the banner: one is a larger area which provides space for the posts that are published to the blog on a fairly regular schedule. The other column(s) is usually less wide than the main area and is commonly referred to as a sidebar. The sidebar is often used for content that is updated less often, thus remaining rather constant. Typical sections that may be included in the sidebar: a calendar containing links on the days the blog author posted, a search field, archive links to previous posts, and links to the categories used in the blog among other options such as widgets. For the knowledgeable user, the sidebar can be customized to suit needs and taste.
