Hi Tosin,
Thank you for the question.

1. Doing server side check does not provide right user experience. So, I do not recommend the above code. The code does not include any validation function, it just lets the implementer define their own logic.

2. If you still wish to implement server side checkup, you can include this library https://github.com/bjeavons/zxcvbn-php and use it.

WordPress does not include any php function for testing the password strength currently. It does include the zxcvbn javascript library to test it at the client side(Which BuddyPress already uses).

Hi Carsten,
Thank you for the question.

The page id selector should work fine. Have you checked your the css specificity? Your css may begetting overridden. Please check in the developer console using the element inspector.

Hi Carsten,
I personally think using css is your best option here.

Hi John,
Thank you for the question.

I am posting a sample code below for the settings page. Please update with your custom validation check.

// add validation logic to BuddyPress password update.
add_filter( 'bp_members_validate_user_password', function ( $errors, $pass, $confirm_pass, $userdata ) {
	// already has error.
	if ( $errors->has_errors() ) {
		return $errors;
	}

	// add your validation logic here.
	$is_strong_password = false;// set it to true/false based on your validation logic.

	if ( ! $is_strong_password ) {
		$errors->add( 'weak_password', __( 'Please use strong password.' ) );
	}

	return $errors;
}, 10, 4 );

You can update the validation logic by using your validate_password to achieve your goal.

hope that helps.
