Display Something in the Header After All Styles are Loaded

Question

I'd like to include a functionality in a theme that will overwrite styles from previously included CSS files. For this purpose, I need to be able to display a <style> in the header after ALL stylesheets have been displayed.

Is there a hook to do this?

Answer 1

Hook to wp_enqueue_scripts with a high priority number. For example:

function load_my_style_wpse_90225() {
  wp_register_style( 'mystyle', get_template_directory_uri() .'/path/to/stylesheet.css');
  wp_enqueue_style( 'mystyle' );
}
add_action('wp_enqueue_scripts','load_my_style_wpse_90225',1000);

That should reasonably load last in line.

Basically the same answer as here: Wooslider custom css

Answer 2

Although it is generally not recommended, we can hook to the [wp_print_styles][1] action, which displays after wp_head, wp_enqueue_scripts, and wp_enqueue_styles.

So (in functions.php):

function my_theme_custom_css_handler(){
    echo '<style>custom css here</style>';
}
add_action('wp_print_styles', 'my_theme_custom_css_handler');
