Cannot keep footer at bottom in bootstrap modal fullscreen

Question

I'm trying to keep the footer of bootstrap modal to bottom but I can't, this is my html structure:

<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Essentially I want display the modal at fullscreen mode, this working good, but the footer doesn't go to bottom.

Css:

.modal-dialog {
 width: 100%;
  height: 100%;
  padding: 0;
}

.modal-content {
  height: 100%;
  border-radius: 0;
}

I create a jsfiddle that explain the situation:

Answer 1

You can give the model-content a relative position and modal-footer position absolute with bottom 0px;

Try with

.modal-content {
  height: 100%;
  border-radius: 0;
  position:relative;
}

.modal-footer {
  border-radius: 0;
  bottom:0px;
  position:absolute;
  width:100%;
}

Everything works fine, my friend.

Jsfiddle

  width: 100%;
  height: 100%;
  padding: 0;
}

.modal-content {
  height: 100%;
  border-radius: 0;
}

.modal-footer {
  position: absolute;
  bottom: 0;
  width: 100%;
}
