body: <p>How can I hide the value of a button, while still showing the button?  I am using color: transparent; but that doesn't work.  </p>
  
  <p>I want to hid the value of the button, but not all of the button.  I need to keep the value attribute in the button; I just don't want it to be visible.  </p>
