Styling the WordPress customization section

To style the WordPress settings section, I have introduced my style file to WordPress using the following code:

 function WordPress_style_management()
{
  echo wp_enqueue_style( 'WordPress', get_template_directory_uri() . '/style.css', array(), '4.0.0' );
}
add_action( 'admin_head', 'WordPress_style_management' );

This code works correctly and all styles are correctly applied to the WordPress settings section.

But the problem that happened to me is that I can’t give any style to the customization section of WordPress.

Is there a code like above so I can style the customization section as well?
