Bootstrap Modal Footer Button Full Width

im trying to center and expand the "Close" button to its full width: https://i.sstatic.net/ogBsV.png

Code so far:

<div class="modal-dialog">
 <div class="modal-content">
    <div class="modal-header">
        <h5 class="modal-title modalHeading" id="ariaangebote">Title</h5>
    </div>
    <div class="modal-body">
    </div>
    <div class="modal-footer">
        <button type="button" class="btn mainBtn btn-block" data-bs-dismiss="modal">
            Close
        </button>
    </div>
</div>

Thank you

Solution

  • Bootstrap-5 doesn't have btn-block anymore like Bootstrap 4 used to (Documentation). Its now controlled with grid/flex. In your code, modal-footer class is already a flex by default. So all you need do to is add the class col-12 (or any other value if you want to change the width) to the button. It'll become a block button.
