rec19 on "hook to customise the lost password screen"

Hello,

I'm no coder, just do some css.

I've already got:

add_action('admin_head', 'custom_admin');
function custom_admin() {
   echo '<style type="text/css">
css code here
	</style>';
}

add_action('login_form', 'custom_login');
function custom_login() {
   echo '<style type="text/css">
css code here
	</style>';
}

I've tried:

add_action('password_reset', 'custom_password_reset');
function custom_password_reset() {
   echo '<style type="text/css">
css code here
	</style>';
}

But it doesn't work.
