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 The -moz-box-direction will only be used for XUL while the previous standard box-direction has been replaced by flex-direction.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.
| Initial value | normal |
|---|---|
| Applies to | elements with a CSS display value of box or inline-box |
| Inherited | no |
| Media | visual |
| Computed value | as specified |
| Animation type | discrete |
| Canonical order | the unique non-ambiguous order defined by the formal grammar |
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.

[1] In addition to the -moz prefixed support, Gecko 48.0 (Firefox 48.0 / Thunderbird 48.0 / SeaMonkey 2.45) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.
