title: Bootstrap 3 col-sm-offset-x affects to the col-md-x structure
body: <p>I have this code <code>&lt;div class="col col-md-12 col-sm-6 col-sm-offset-1 hidden-xs"&gt;</code> and bootstrap is making the offset to the col-md-12 too, I'm checking the code and I have no clue why this is happening, I think that this wasn't happening before, but I have go back a lot of steps in the code maybe to the point it was working and nothing.</p>
  
  <p>If I remove the offset it works as suppose...but I don't have the offset on smaller resolutions.</p>
  
  <p>This is the page where you can see the problem: <a href="http://sociedadrealyantigua.com/movil/">Test page</a></p>
  
  <p>Is the block where it puts "Especial 52º Aniversario"</p>
  
  <p>Thanks for the help, is driving me nuts</p>
