The CSS order property specifies the order used to lay out flex items in their flex container. Elements are laid out in the ascending order of the order value. Elements with the same order value are laid out in the order in which they appear in the source code.

Note: order is only meant to affect the visual order of elements and not their logical or tab order. order must not be used on non-visual media such as speech.

Formal syntax



Here is a basic HTML chunk:

<!DOCTYPE html>
<div id='main'>

The following CSS code should create a classic two-sidebar layout surrounding a content block. The Flexible Box Layout Module automatically creates blocks of equal vertical size and uses as much horizontal space as available.

#main { display: flex; }
#main > article { flex:1;         order: 2; }
#main > nav     { width: 200px;   order: 1; }
#main > aside   { width: 200px;   order: 3; }

[1] To activate Flexbox support for Firefox 18 and 19, the user change the about:config preference layout.css.flexbox.enabled to true. Multi-line flexible boxes are supported since Firefox 28.

Firefox currently incorrectly changes the tab order of elements. See bug 812687.

[2] In Internet Explorer 10, a flexible container is declared using display:-ms-flexbox and not display:flex. The property is implemented under the non-standard name -ms-flex-order.
