Hide a div to subscribers(user role) in one page (is_page)

Just hiding a div is insecure – they can easily unhide it by editing the source or executing some Javascript in the browser’s URL bar.
I believe this may be what you’re looking for:

<?php
if (current_user_can(‘subscriber’)){
?>

[html here]

<?php
}
?>
