A sidebar is a vertical column provided by a theme for displaying information other than the main content of the web page. Themes usually provide at least one sidebar at the left or right of the content. Sidebars usually contain widgets that an administrator of the site can customize.
In a theme, sidebars are generated by a template file, typically named sidebar.php.
