Prevent input zoom on mobile

Hi,

I would like to prevent the automatic zoom in when you’re filling in form fields/checkout fields on mobile. It’s very annoying.

I have found this snippet:

add_filter('ocean_meta_viewport', 'owp_child_viewport');
function owp_child_viewport( $viewport ){
	$viewport = '<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0">';
	return $viewport;
}

It seems like this snippet does the job but I wanted to make sure it’s up to date because it was posted 3 years ago. Is this snippet correct?

Thanks
