title: Bootstrap 3: text-align change at breakpoint?
body: <p>Is there a built-in way in Bootstrap 3.x to set/remove a class like "text-right"?</p>
  
  <p>For example, I have a column <code>&lt;div class="col-md-6 text-right"&gt;</code> but at xs size I don't want the text-right to apply.</p>
  
  <p>I know how to do this with my own classes/media queries but was wondering if there was something simple built in.</p>
