    A basic example (from Hello Dolly plugin code):

    function dolly_css() {
	// This makes sure that the positioning is also good for right-to-left languages
	$x = is_rtl() ? 'left' : 'right';

	echo "
	<style type='text/css'>
	#dolly {
		float: $x;
		padding-$x: 15px;
		padding-top: 5px;
		margin: 0;
		font-size: 11px;
	}
	</style>
	";
}
add_action( 'admin_head', 'dolly_css' );

    Example migrated from Codex:

    This example adds an inline CSS style to admin_head so the welcome message option from dashboard is removed; you can make and customize your own function and add it the same way.

    <?php 

// Add inline CSS in the admin head with the style tag
function my_custom_admin_head() {
	echo '<style>[for="wp_welcome_panel-hide"] {display: none !important;}</style>';
}
add_action( 'admin_head', 'my_custom_admin_head' );
?>

    Example migrated from Codex:

    In this example, console.log is added, which will only be executed on the admin side.

    <?php
// Add inline JS in the admin head with the <script> tag

function my_custom_admin_head() {
	echo '<script type="text/javascript">console.log(\'admin script\')</script>';
}
add_action( 'admin_head', 'my_custom_admin_head' );
?>
