排队的css文件不起作用

Question

我设法将css文件放入子主题中，但css文件不起作用！！为什么？代码是正确的，此代码在子主题的样式文件中工作

function enqueue_pure_styles() {
$suffix = '';
if (is_single()) {
$suffix = '.xdovom';
} 
wp_enqueue_style('pure-styles', get_stylesheet_directory_uri().'/styles'.$suffix.'.pure.css');

}

// enqueue our purified css file
add_action('wp_print_styles', 'enqueue_pure_styles', PHP_INT_MAX);
