What are the template tags in WordPress?

A template tag is a code that instructs WordPress to “do” or “get” something. Like in header.php we will use the tag bloginfo(‘name’) to get “Site Title” from the wp-options table which is set in Setting > General at WordPress dashboard. The the_title() template tag is used to display the post title. wp_list_cats() is for display categories. get_header() for getting header. get_sidebar() for display the sidebar on page. get_footer() for get the footer content on page.
