Optimize the delivery of CSS

Hello.
PageSpeed ​​google tells me :

Items that you might consider correct :
Remove the blocking JavaScript and CSS display the contents of the upper half of the page
Your page has 1 CSS resources causing a blockage . This causes a delay in the processing of the page.
Unable to display the contents of the upper half of the page without having to wait for any of the resources are loaded. Try to postpone or load resources asynchronously blocking viewing or copying portions reviews of these resources directly into the HTML.

Optimize the delivery of CSS of these URLs :
http://massatgesfuji.com/ … ogle-maps/css/wpgmza_style.css ? ver = 3.8.1

This is a problem that had already been previously with other css and js , but that had been solved with this code:

function footer_enqueue_scripts() {
remove_action(‘wp_head’, ‘wp_print_scripts’);
remove_action(‘wp_head’, ‘wp_print_head_scripts’, 9);
remove_action(‘wp_head’, ‘wp_enqueue_scripts’, 1);
add_action(‘wp_footer’, ‘wp_print_scripts’, 5);
add_action(‘wp_footer’, ‘wp_enqueue_scripts’, 5);
add_action(‘wp_footer’, ‘wp_print_head_scripts’, 5);
}
add_action(‘after_setup_theme’, ‘footer_enqueue_scripts’);

but with this , I can not and I ‘ve tried variations and other codes , but only to reappear get other css and js that had already shifted above.
any solution you can think of ?
thanks …
