title: onclick button border color change
body: <p>Should be fairly simple but I'm lost and all searches result in non-specific answers that don't directly relate to my issue.</p>
  
  <p>Button, border is black but apparently, the "depressed" feel is achieved by changing the border color to black so when I do click the button, it feels "dead". Nothing happens, so it's hard to tell if you miss-clicked or what. </p>
  
  <p>How do you change the "onclick" border color? That way, it can get that "depressed" look again. </p>
  
  <pre><code>.addButton {
  border-color:black;
  border-width:1px;
  background-color:#00B0F0;
  text-decoration:underline;
  }
  </code></pre>
