I am trying to vertically align this button in the center of the modal-footer div.  Here is a link to my JSFiddle: https://jsfiddle.net/kris_redden/34jyLpok/
.modal-footer {
  background-color: #2A3E5D;
  color: white;
  height: 100px;
  padding: 2px 16px;
}
.wrapper-div {
  vertical-align: middle
}
.button {
  background: #e8e8e8;
  display: inline-block;
  font-size: 12px position: relative;
}<div class="modal-footer">
  <div class="wrapper-div">
    <button type="button" class="button"> Submit Filters </button>
  </div>
</div>I'm not sure what needs to change in order for this to be vertically aligned in the center of the blue modal-footer div. I know can accomplish this in a hacky way by putting margins on the button but that isn't what I want to do.
