Adding a function in the head tag
We will next see how to enter a function called wp_head() in the <head> tag. This puts any additional information that is needed into the head tag. For example, when you install a plugin and, let's say, it needs to include a style sheet, or it needs to do something in the head, to do this we need to enter the following code. So when you create plugins, you can have stuff pop out right in the head:
<!DOCTYPE html>
<html <? php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo('charset'); ?>">
<title><?php bloginfo('name'); ?></title>
<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>">
<?php wp_head(); ?>
