Stacked progressbars

[topherreynoso]

Love the work you've done here, making it easy for me to animate but am I missing something? This is just rendering the progress bars each starting at 0 so one always covers another instead of actually stacking them as expected.

<div class="progress">
  <div class="bar bar-success" aria-valuetransitiongoal="10"></div>
  <div class="bar bar-warning" aria-valuetransitiongoal="10"></div>
</div>

$('.bar').progressbar();
