(if understand correctly, want hovered element overflow parent container going outside box. however, css3 columns designed such overflow continue @ top of next column, , there's no way i'm aware of change behavior). i recommend using different approach achieve ui you're after, such using jquery insert wrappers around each column. however, if you're set on using column-count, may able hack doing this: jsfiddle: http://jsfiddle.net/p6r9p/ css...
