column-fill is the one missing CSS property from the multicol spec (not counting break-after, break-before or break-inside, which really belong in a more generic spec for fragmentation). This property is used to tell the engine whether columns should be balanced or not. If they are balanced, each column gets similar amounts of content inside. If they are not balanced, each column will be filled to the height of the multicol container, until we run out of content.
