Use align-items utilities on flexbox containers to change the alignment of flex items on the cross axis (the y-axis to start, x-axis if flex-direction: column). Choose from start, end, center, baseline, or stretch (browser default).
Quick reference
| Class | Properties |
|---|---|
.align-items-start | align-items: flex-start; |
.align-items-end | align-items: flex-end; |
.align-items-center | align-items: center; |
.align-items-baseline | align-items: baseline; |
.align-items-stretch | align-items: stretch; |
Basic usage
Stretch
Use align-items-stretch to stretch items to fill the container’s cross axis. This is the browser default behavior.
<div class="d-flex align-items-stretch gap-4">
<div class="py-2">01</div>
<div class="py-6">02</div>
<div class="py-5">03</div>
</div>
Start
Use align-items-start to align items to the start of the container’s cross axis:
<div class="d-flex align-items-start gap-4">
<div class="py-2">01</div>
<div class="py-6">02</div>
<div class="py-5">03</div>
</div>
Center
Use align-items-center to align items along the center of the container’s cross axis:
<div class="d-flex align-items-center ...">
<div class="py-2">01</div>
<div class="py-6">02</div>
<div class="py-5">03</div>
</div>
End
Use align-items-end to align items to the end of the container’s cross axis:
<div class="d-flex align-items-end ...">
<div class="py-2">01</div>
<div class="py-6">02</div>
<div class="py-5">03</div>
</div>
Baseline
Use align-items-baseline to align items along the container’s cross axis such that all of their baselines align:
<div class="d-flex align-items-baseline gap-4">
<div class="pt-2 pb-4">01</div>
<div class="pt-6 pb-5">02</div>
<div class="pt-5 pb-3">03</div>
</div>
Breakpoints
All align-items utilities that supports responsive at specific breakpoints, from xs to xxl, have no breakpoint abbreviation in them.
The responsive classes are named using the format align-items-{breakpoint}-{value}.
.align-items-sm-start.align-items-sm-end.align-items-sm-center.align-items-sm-baseline.align-items-sm-stretch.align-items-md-start.align-items-md-end.align-items-md-center.align-items-md-baseline.align-items-md-stretch.align-items-lg-start.align-items-lg-end.align-items-lg-center.align-items-lg-baseline.align-items-lg-stretch.align-items-xl-start.align-items-xl-end.align-items-xl-center.align-items-xl-baseline.align-items-xl-stretch.align-items-xxl-start.align-items-xxl-end.align-items-xxl-center.align-items-xxl-baseline.align-items-xxl-stretch
For example, use align-items-md-center to apply the items-center utility at only medium screen sizes and above.
<div class="d-flex align-items-stretch align-items-md-center">
<!-- ... -->
</div>
