body: <p>how do I stretch a form submit button using CSS?
  I'd like to have some kind of horizontal padding between the text inside the button and the button left and right end. Is this possible, and if so, how?</p>

  <p>Tips for making the button prettier (without using images) are also much appreciated :-).</p>
