/* .button gives an <a> the same look as the yellow <button>. Setting an explicit display here is
   what makes the [hidden] override below necessary: an author-stylesheet display rule always beats
   the user-agent's [hidden] { display: none }, regardless of selector specificity, so without the
   override a hidden .button would still take layout space and be clickable. */
