box-align
=========

**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.

**Deprecated:** This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

**Warning:** This is a property of the original CSS Flexible Box Layout Module draft, and has been replaced by a newer standard.

The **`box-align`** CSS property specifies how an element aligns its contents across its layout in a perpendicular direction. The effect of the property is only visible if there is extra space in the box.

See flexbox for information about the current standard.

The direction of layout depends on the element's orientation: horizontal or vertical.

Syntax
------


```css
/\* Keyword values \*/
box-align: start;
box-align: center;
box-align: end;
box-align: baseline;
box-align: stretch;

/\* Global values \*/
box-lines: inherit;
box-lines: initial;
box-lines: unset;
```


The `box-align` property is specified as one of the keyword values listed below.

### Values

`start`

The box aligns contents at the start, leaving any extra space at the end.

`center`

The box aligns contents in the center, dividing any extra space equally between the start and the end.

`end`

The box aligns contents at the end, leaving any extra space at the start.

`baseline`

The box aligns the baselines of the contents (lining up the text). This only applies if the box's orientation is horizontal.

`stretch`

The box stretches the contents so that there is no extra space in the box.

Notes
-----

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

* For horizontal elements, the *start* is the top edge.
* For vertical elements, the *start* is the left edge.

The edge opposite to the start is designated the *end*.

If the alignment is set using the element's `align` attribute, then the style is ignored.
