Php 自定义Wordpress登录到中心CSS

我有一个简单的CSS问题，将内容对齐到中心，基本上我在左侧有一个徽标，在右侧有登录输入。这是我的function.php代码

function custom_login_css() 
{
    echo '<link rel="stylesheet" type="text/css" href="'.get_stylesheet_directory_uri().'/login/login-styles.css" >';
}
add_action('login_head', 'custom_login_css');

我还将包括一张我心目中的图像。

尝试将输入字段和徽标设置为显示块，然后应用所需的CSS将其居中。

相反，将这段庞大的代码制作成一个小提琴，这将帮助我们了解真正发生的事情。为什么不使用呢？这是在wordpress中，我相信小提琴在那里不起作用。但那不是我的问题
