Wells
The .well class adds a rounded border around an element with a 
gray background color and some padding:

  Normal Well
  Large Well
Change the size of the well by adding the .well-sm 
class for 
small wells or  .well-lg class for large wells:
Example
 <div class="well well-sm">Small Well</div>
<div class="well well-lg">Large Well</div>

By default, wells are medium in size.
