The column-fill CSS property controls how contents are partitioned into columns. Contents are either balanced, which means that contents in all columns will have the same height or, when using auto, just take up the room the content needs.

  • Initial value balance
  • Applies to multicol elements
  • Inherited no
  • Media visual, but, in continuous media, has no effect in overflow columns
  • Computed value as specified
  • Animatable no
  • Canonical order the unique non-ambiguous order defined by the formal grammar


column-fill: auto;
column-fill: balance;

/* Global values */
column-fill: inherit;
column-fill: initial;
column-fill: unset;
