Answer

Bootstrap provides utility classes that make it easy to add responsive margins to components like cards. You can use classes such as `m-sm-3`, `m-md-4`, etc., to control the margin at different breakpoints.

<!-- BEGIN COPY / PASTE -->
        <div class="card m-3 m-md-4">
            <div class="card-body">
                <h5 class="card-title">Responsive Card</h5>
                <p class="card-text">This card has responsive margins.</p>
            </div>
        </div>
        <!-- END COPY / PASTE -->

Additional Comment:

The `m-3` class adds a uniform margin on all sides for extra small to small screens.
The `m-md-4` class increases the margin on medium and larger screens.
You can adjust the numbers (e.g., `m-1`, `m-2`, etc.) to change the margin size.
Use `mt-`, `mb-`, `ml-`, `mr-` for top, bottom, left, and right margins specifically if needed.
