Per CSS spec column-width is not a strictly fixed width.

http://www.w3.org/TR/css3-multicol/#cw
<length> 
describes the optimal column width. The actual column width may be wider (to fill the available space), or narrower (only if the available space is smaller than the specified column width). Specified values must be greater than 0.
