Remove Block Library CSS on Frontend

WordPress loads wp-block-library.css on every page, even when the site does not use blocks. If your theme does not use Gutenberg blocks, you can remove it. Add to your functions.php file. For more on CSS optimization.

add_action( 'wp_enqueue_scripts', function() {
	wp_dequeue_style( 'wp-block-library' );
	wp_dequeue_style( 'wp-block-library-theme' );
	wp_dequeue_style( 'global-styles' );
}, 100 );

Note: If the page has block content, the CSS may break.
