I've just tried to use this example and it appears that there's been zero consideration to any form of accessible features here.

The show example "button" is a non-focusable div element

  <div class="button" onclick="window.examples['theme-modern']()">Show Example</div>

Once the window is open, the minimise, maximise, full-screen and close "buttons" are spans containing no useful text.

  <span class="wb-min"></span>
  <span class="wb-max"></span>
  <span class="wb-full"></span>
  <span class="wb-close"></span>

The list goes on...

Sure, sometimes accessibility can be hard to get right but it's quite something for it to have been completely disregarded.
