The order
CSS property sets the order to lay out an item in a flex or grid container. Items in a container are sorted by ascending order
value and then by their source code order.

Syntax
/* <integer> values */ order: 5; order: -5; /* Global values */ order: inherit; order: initial; order: unset;
Since 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.
Values
<integer>
- Represents the ordinal group to be used by the item.
Accessibility concerns
Using the order
property will create a disconnect between the visual presentation of content and DOM order. This will adversely affect users experiencing low vision navigating with the aid of assistive technology such as a screen reader. If the visual (css) order is important, then screen reader users will not have access to the correct reading order.

Examples
Ordering items in a flex container
This example uses CSS to 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.
HTML
<header>...</header> <main> <article>Article</article> <nav>Nav</nav> <aside>Aside</aside> </main> <footer>...</footer>
CSS
main { display: flex; text-align:center; } main > article { flex:1; order: 2; } main > nav { width: 200px; order: 1; } main > aside { width: 200px; order: 3; }
