Warning: This property reflects an old version of the CSS Flexible Box Layout Module standard. The -moz-box-direction will only be used for XUL while the previous standard box-direction has been replaced by flex-direction.

See Flexbox for more information.

Summary

The CSS box-direction property specifies whether a box lays out its contents normally (from the top or left edge), or in reverse (from the bottom or right edge). See Flexbox for more about the properties of flexbox elements.

Syntax

normal | reverse | inherit

Values

normal
The box lays out its contents from the start (the left or top edge).
reverse
The box lays out its contents from the end (the right or bottom edge).

Examples

.example {
  /* bottom-to-top layout */
  -moz-box-direction: reverse;      /* Mozilla */
  -webkit-box-direction: reverse;   /* WebKit */
  box-direction: reverse;           /* As specified */
}

Notes

The edge of the box designated the start for layout purposes depends on the box's orientation:

Horizontal left
Vertical top

The edge opposite to the start is designated the end.

If the direction is set using the element's dir attribute, then the style is ignored.
