Updated 2018  In Bootstrap 4  the centering methods have changed    Horizontal Center in BS4   text-center is still used for display inline elements mx-auto replaces center-block to center display flex children offset-  or mx-auto can be used to center grid columns   mx-auto  auto x-axis margins  will center display block or display flex elements that have a defined width      vw  px  etc     Flexbox is used by default on grid columns  so there are also various flexbox centering methods   Demo Bootstrap 4 Horizontal Centering  For vertical centering in BS4 see https   stackoverflow com a 41464397 171456

Update  while this answer was likely correct back in early 2013  it should not be used anymore  The proper solution uses offsets     As for other users suggestion there are also native bootstrap classes available like   class  text-center  class  pagination-centered    thanks to  Henning and  trejder
