I am writing code in functions.php :
function add_theme_styles() { wp_register_style('main', get_template_directory_uri() . '/css/main.css'); wp_enqueue_style('main'); } add_action('wp_enqueue_scripts', 'add_theme_styles'); Styles are not loaded. In header.php there is wp_head() . Tell me, please, what could be the problem?
