Customizing the Footer
You can customize the footer by going to Admin → Configuration → Branding, in the footer tab. On default there's no configuration and the interface will look like this:
You can use either left, middle, center or the full with option, or use the Advanced Design with full HTML as needed.
Added Terms and Conditions Modal
<button class="btn btn-outline-secondary" data-bs-toggle="modal" data-bs-target="#termsmodal"> Terms & Conditions </button>
This configuration can be found in Admin → Branding → Footer.
The footer can be used for branding, displaying T&C's and so on. Here's a starting point that you can paste for instance in the middle column:
<button class="btn btn-outline-secondary" data-bs-toggle="modal" data-bs-target="#terms_and_conditions"> Terms & Conditions </button> <div class="modal fade" id="terms_and_conditions" tabindex="-1"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Terms & Conditions</h5> <button class="btn-close" data-bs-dismiss="modal"></button> </div> <div class="modal-body"> Some Terms & Conditions... </div> <div class="modal-footer"> <button class="btn btn-outline-secondary" data-bs-dismiss="modal">Close</button> </div> </div> </div> </div>
