How to pin a column in bootstrap?

Question

Bootstrap

There is a grid: content on the left and sidebar on the right, I'm trying to make sure that the sidebar is always pinned in the same place where it is. When I add the position-fixed class to it, it is fixed but moved to the left column.
jsfiddle

Answer 1

.position-fixed {
  right: 30px;
  top: 0;
}
