Display
Display utilities switch the CSS display value: d-none, d-inline, d-inline-block, d-block, d-grid, d-flex, d-inline-flex and the table values. Add a breakpoint (d-md-flex, d-lg-none) to show, hide or re-flow an element from a screen size up, and d-print-* to control what appears on paper.
1Inline versus block
d-inline elements sit side by side and ignore width; d-block elements take a full row.

<button type="button" class="btn btn-primary">Continue</button>
<button type="button" class="btn btn-outline-secondary">Back</button>
