Gap utilities
Gap utilities space out the children of flex and grid containers without margins on each child.
In this page:
Syntax
<div class="d-flex gap-3">
<div>item</div>
<div>item</div>
</div>Gap utilities
On a .d-flex or .d-grid container, .gap-3 adds equal space between children. Use .row-gap-* and .column-gap-* for one direction. In the grid system the equivalent are gutter classes g-*, gx-* and gy-*.
Note:
gap works on flex and grid containers only.
