Positions

Enable the both vertically and horizontally alignment with a position utilities.

Centering

Assuming the parent element has position: relative;, these properties will center a child element both horizontally and vertically inside, no matter what the width of height of either are.

I am centered.
<div class="position-relative bg-primary" style="width: 200px; height: 200px;">
  <div class="bg-white position-absolute position-centered p-3">I am centered.</div>
</div>
