WordPress: Disabling Plugin Stylesheet

You must have seen that WordPress plugins can slow your site down with additional HTTP Requests such as adding their own stylesheet. For advanced users, who are adding custom styles for the announcement, you do not need to have an additional HTTP request for a useless stylesheet. Then add the following function in your theme’s functions.php file:

<?php
add_action( 'wp_print_styles', 'my_deregister_styles', 100 );
    function my_deregister_styles() {
    wp_deregister_style( 'ninja-annc-css' );
}
?>
