title: Bootstrap: how to add vertical offset in columns?
body: <p>Bootstrap provides a class <code>col-sm-offset-*</code> to add spaces between columns. It is working fine on laptop screen but when we change screen resolution to mobile it displays columns arranged one below another without space.</p>
  
  <p>Is there any class in bootstrap lib using which we can achieve expected result.</p>
