Answer 1

Reckon you could do something like this:

<?php
    if ($condition == true): 
         echo 'ITS TRUE!'; 
    else: 
?> 
    //put whatever html/style/script you want here, for example
    <script>
        $( '#id-element' ).css('display', 'none');
    </script>
<?php endif; ?>

Answer 2

You can echo the HTML for a style element and throw the CSS inside that.

else {
    echo '<style type="text/css">
        #id-element {
            display: none;
        }
        </style>';
}
