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

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

    • Initial value 0
    • Applies to flex items and absolutely-positioned flex container children
    • Inherited no
    • Media visual
    • Computed value as specified
    • Animatable yes, as an integer
    • Canonical order the unique non-ambiguous order defined by the formal grammar

    See Using CSS flexible boxes for more properties and information.


    Formal syntax: <integer>
    order: 5
    order: inherit


    Represents the ordinal group the flex item has been assigned.


    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; }
