To add spacing between Bootstrap buttons, you can use Bootstrap's spacing utility classes. These classes allow you to add margin or padding to elements easily. For buttons, you can use margin classes like "me-2" (margin-end) to add space between them.

<!-- BEGIN COPY / PASTE -->
        <button type="button" class="btn btn-primary me-2">Button 1</button>
        <button type="button" class="btn btn-secondary">Button 2</button>
        <!-- END COPY / PASTE -->

1. The "me-2" class adds a small margin to the end (right side in LTR languages) of the first button.
2. You can adjust the spacing by using "me-1", "me-3", etc., for different margin sizes.
3. These classes are responsive and work well with Bootstrap's grid system.
