angularjs 垂直居中角引导模态窗

我怎样才能垂直居中这个模态窗口,而不管显示的内容的大小。在我的网页,我显示一个图像作为一个模态窗口,我想它显示在屏幕的中心。我可以水平对齐,但我不能让它垂直合作。有没有这样做的想法/例子?
我在我的页面中使用了这个例子:modal window demo plunker
但我的模态窗口的实际内容看起来像这样:

<script type="text/ng-template" id="myModalContent.html">
        <div>
             <img class= "attachmentImage" src={{items}} />
        </div>
</script>

我应该在bootstrap.min.cssui-bootstrap-tpls-0.13.0.js中进行更改,还是在我自己的工作表中使用我的样式来实现这一点的最佳方法。
非常感谢你的时间。让我知道如果你需要更多的信息或如果我不清楚。

我强烈不同意1Bladesforhire的回答,因为当modal容器的顶部高于视口高度时,它就变得无法访问。这是使用absolute垂直居中方法将比父级高的子级居中时的常见问题。
我首选的垂直居中Bootstrap模型的方法是

.modal-dialog {
  display: flex;
  flex-direction: column;
  justify-content: center;
  overflow-y: auto;
  min-height: calc(100vh - 60px);
}
@media (max-width: 767px) {
  .modal-dialog {
    min-height: calc(100vh - 20px);
  }
}

/* you only need the above CSS. The code below centers the modal trigger button */

body {
  display: flex;
  align-items: center;
  justify-content: center;
  min-height: 100vh;
}

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

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

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></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>

当垂直居中时,当小于视口高度时,.modal-content仍然是完全可访问的(即使高度为300vh):

.modal-dialog {
  display: flex;
  flex-direction: column;
  justify-content: center;
  overflow-y: auto;
  min-height: calc(100vh - 60px);
}
@media (max-width: 767px) {
  .modal-dialog {
    min-height: calc(100vh - 20px);
  }
}

/* you only need the above CSS. The code below centers the modal trigger button */

.modal-content {
  height: 300vh;
}

body {
  display: flex;
  align-items: center;
  justify-content: center;
  min-height: 100vh;
}

    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></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>
