You can do a little adjustment to leave a blank line at the top.

Like this.

        <script type="text/javascript" >
            alert("USER NOTICE "  +"\n"
            +"\n"
            +"New users are not allowed to work " +"\n"
            +"with that feature.");
        </script>

There s quite a nice  hack  here - https   stackoverflow com a 14565029 where you use an iframe with an empty src to generate the alert   confirm message - it doesn t work on Android  for security s sake  - but may suit your scenario
