Order
Change the visual order of specific flex items with a handful of order utilities. We only provide options for making an item first or last, as well as a reset to use the DOM order.
Code Example
<div class="d-flex flex-nowrap bg-light"> <div class="order-3 p-2 bg-light">First flex item</div> <div class="order-2 p-2 bg-light">Second flex item</div> <div class="order-1 p-2 bg-light">Third flex item</div> </div>
Align content
Use align-content utilities on flexbox containers to align flex items together on the cross axis. Choose from start (browser default), end, center, between, around, or stretch. To demonstrate these utilities, we’ve enforced flex-wrap: wrap and increased the number of flex items.
Code Example
<div class="d-flex align-content-start flex-wrap"> ... </div> <div class="d-flex align-content-end flex-wrap">...</div>
