Custom Bootstarp Componets

Hi

I was wondering why we cant use custom boostarp componets like http://getbootstrap.com/components/#input-groups-sizing

<div class="input-group input-group-lg">
  <span class="input-group-addon">@</span>
  <input type="text" class="form-control" placeholder="Username">
</div>

and not get the styling associated with that class. Isn’t the theme based of bootstrap , shouldn’t these elements work ?

hi,
the theme is using bootstrap, but only some components, elements that we find it suitable for our theme.

Thanks for you message.
