box-ordinal-group

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

This is a property of the original CSS Flexible Box Layout Module draft, and has been replaced by a newer standard. See flexbox for information about the current standard.

The box-ordinal-group CSS property assigns the flexbox's child elements to an ordinal group.

/* <integer> values */
box-ordinal-group: 1;
box-ordinal-group: 5;

/* Global values */
box-ordinal-group: inherit;
box-ordinal-group: initial;
box-ordinal-group: unset;

Ordinal groups may be used in conjunction with the box-direction property to control the order in which the direct children of a box appear. When the computed box-direction is normal, a box will display its elements starting from the lowest numbered ordinal group and ensure that those elements appear to the left (for horizontal boxes) or at the top (for vertical boxes) of the container. Elements with the same ordinal group are flowed in the order they appear in the source document tree. In the reverse direction, the ordinal groups are examined in the same order, except the elements appear reversed.

Syntax

The box-ordinal-group property is specified as any positive <integer>.

Examples

Basic usage example

In an older version of the spec, box-ordinal-group was included to allow you to change the display order of flex children inside a flex container:

article:nth-child(1) {
  -webkit-box-ordinal-group: 2
  -moz-box-ordinal-group: 2
  box-ordinal-group: 2
}

article:nth-child(2) {
  -webkit-box-ordinal-group: 1
  -moz-box-ordinal-group: 1
  box-ordinal-group: 1
}

The modern flexbox equivalent is order.
