New version after SMF Customization Team advised:
While testing your customization, we received the following issues:
- When adding the style tag you need to specify the type attribute. e.g. type="text/css" to prevent errors in validation.
- Also you could instead add this tag to the $context['html_headers'] var instead. e.g. $context['html_headers'] .= <style type="text/css"> css </style>
