The css file that is enqueued does not work-CodePudding

I managed to enqueue a css file in the child theme but the css file didn't work!! Why? The code is correct, this code works in the style file of the child theme

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);

Use wp_enqueue_scripts instead of wp_print_styles
