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

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>
