Need to move it to the middle:

A:

Specify the parent container as position: relative or position: absolute.
Specify a fixed height on the child container.
Set position: absolute and top: 50% on the child container to move the top down to the middle of the parent.
Set margin-top: -yy where yy is half the height of the child container to offset the item up.

(http://phrogz.net/CSS/vertical-align/)

Either relatively position.columns  (position: relative) or absolutely position it  (position: absolute)
Give.column a height value
Absolutely position.column  (position: absolute), and give it top: 50%
Give.column a top margin of the negative of half its height value  (margin-top: -yy where yy is half of the height of.column)
