Hello readers !
Today We will discuss about sidebar.php

This is one of the best features in WordPress that gave lot of flexibility in theme. Sidebar.php is a template page in your theme directory. It includes some extra links which you cannot show in header menu and footer menu. Admin can customize sidebar.php file. Initially, sidebar were used only as a vertical column provided by a theme for displaying information other than the main content of the web page.

The side can be categories into two parts :- 1-> Dynamic sidebar, and 2-> Sidebar template.

Dynamic Sidebar -: Dynamic Sidebar is a dynamic widget area where you can add single or multiple widgets from your WordPress Dashboard (Appearance => Widgets).
