WordPress5.0+出了个死难用的新版编辑器，默认会在头部加载新版样式

<link rel='stylesheet' id='wp-block-library-css'  href='http://test.blyoo.com/blog/wp-includes/css/dist/block-library/style.min.css?ver=5.0.3' type='text/css' media='all' />

在functions.php函数文件里添加以下去除默认样式

高级版-大神专用版：

//WordPress 5.0+移除 block-library CSS
add_action( 'wp_enqueue_scripts', 'remove_block_library_css', 100 );
function remove_block_library_css() {
	wp_dequeue_style( 'wp-block-library' );
}

简写版-懒人专用版：

add_action( 'wp_enqueue_scripts', function() {
	wp_dequeue_style( 'wp-block-library' );
} );
