You shouldnt be using the @import directive in your stylesheet

It slows things down and can cause some issues for media queries etc.

Instead you should add it to your functions.php file of your child theme:

function yourFunctionName(){
  wp_enqueue_style('themeNameParentStyle', get_template_directory_uri*() . '/style.css', array(), 'all');
}
add_action('wp_enqueue_scripts','yourFunctionName');
