<button onclick=\"window.location='{$_SERVER['PHP_SELF']}';return false;\">Reset</button>
Not enough rep to Vote Up for Kostyan. Here's my final solution (needed a reset button).
Thanks again to Kostyan for answering the question as asked without suggesting a "workaround" (time-consuming) method to "construct a button" with styles.
This is a Button (which the viewer expects to see) and it works exactly as requested. And it mingles with the other buttons on the page. Without complexity.
I did remove the "type=cancel" which apparently was useless. So even less code. :)
