admin_head │ action-hook │ WC 2.1.0

This is a WordPress - admin_head hook. The plugin just uses it.

Fires inside the <head> section on all WordPress admin pages.

Use it to output inline CSS/JS or other HTML markup. The callback does not receive any arguments.

The hook fires on all admin pages. If necessary, limit the output with get_current_screen().

Use admin_enqueue_scripts to enqueue separate CSS and JS files.
