The order Property
The order property changes the visual order of flex and grid items without altering the DOM structure. Default is 0; higher values appear later; negative values appear earlier.
order Basics
Items are displayed from lowest to highest order value. Items with the same order value appear in DOM order.
.nav-logo { order: 0; } /* first */
.nav-links { order: 1; } /* second */
.nav-button { order: 2; } /* last */Negative order
Use negative values to move an item before all default (order:0) items:
.sticky-first {
order: -1; /* appears before all order:0 siblings */
}Responsive Reordering
Change visual order at different breakpoints without changing HTML:
.layout {
display: flex;
flex-direction: column;
}
.main-content { order: 1; }
.sidebar { order: 2; }
@media (min-width: 768px) {
.layout { flex-direction: row; }
.sidebar { order: 0; } /* sidebar first on desktop */
}Important: Accessibility Warning
order changes visual order only. Screen readers and keyboard navigation follow the DOM order, not the visual order. Reordering visually while keeping the DOM in logical reading order is crucial for accessibility.
Tab Order Inconsistency
If you reorder items visually with order, keyboard Tab focus follows the DOM order which may differ from visual order. This creates confusing navigation for keyboard users. Only use visual reordering when it does not break logical sequence.
Common Legitimate Use Cases
Visual reordering is acceptable when:
- The items are not part of a navigable sequence (decorative ordering)
- The visual order matches a natural reading flow that differs from source order for code organization reasons
Flexbox order vs Grid order
The order property works identically in both Flexbox and CSS Grid. It controls the order within the layout algorithm, not the DOM.
order with Flex-wrap
When items wrap to new lines, order determines which items appear on which line and in what sequence within each line.
Reversing All Items
To reverse all items, use flex-direction: row-reverse or column-reverse instead of setting negative order values on every item. It is more semantic and simpler.
.reversed-list {
display: flex;
flex-direction: column-reverse;
/* or row-reverse for horizontal */
}Animation with order
order changes are not animatable in CSS. If you need animated reordering, use transforms or JavaScript-driven animations like Flip.js or GSAP's Flip plugin.
Quick Check
Why should using the order property for reordering navigation links be done cautiously?
Recap
order changes the visual position of flex/grid items without touching HTML. Default is 0; lower values appear first; higher values last. Use it for responsive reordering without changing DOM structure. Always verify that keyboard navigation and screen reader order remain logical when using order reordering.
