How vertically center a popup modal inside a long popup modal

I've got a long full screen popup modal(parent-modal). Inside this modal(parent-modal) there is another popup modal(child-modal). If I scroll the "parent-modal" and then open "child-modal", the "child-modal" modal is not vertically centered.

hope this might be useful to you!

.modal {
}
.vertical-alignment-helper {
    display:table;
    height: 100%;
    width: 100%;
}
.vertical-align-center {
    /* To center vertically */
    display: table-cell;
    vertical-align: middle;
}
.modal-content {
    /* Bootstrap sets the size of the modal in the modal-dialog class, we need to inherit it */
    width:inherit;
    height:inherit;
    /* To center horizontally */
    margin: 0 auto;
}

Try this style with child modal:

#parent-modal{
 position:relative;
}
#child-modal{
  position:absolute;
  top: 50%;
  transform: translateY(-50%);
  -webkit-transform: translateY(-50%);
}
