javascript - Bootstrap 模式未按我的要求显示

Question

我的 Bootstrap 模态在模态的顶部和底部出现蓝线。我不知道为什么蓝线出现在模态框的顶部和底部。我想删除蓝线。我的英语很弱，如果我犯了任何语法或拼写错误，请向我道歉。

HTML 代码:

  <div class="modal fade bs-example-modal-sm vcenter" id="deleteconfirmation" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
  <div class="modal-dialog modal-sm" 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" style="text-align:center">Are you sure you want to Delete it?</h4>
    </div>
    <div class="modal-body">
      <div class="form-group" style="text-align:center">
        <h6>By clicking on Yes button your ad will be Delete.</h6>
      </div>
    </div>
    <div class="modal-footer" style="text-align:center">
      <button type="button" class="btn btn-default" data-dismiss="modal">No</button>
      <button type="button" class="btn btn-primary" id="sayyes">Yes</button>
    </div>
    </div>
  </div>
  </div>

CSS 代码:

.vcenter{
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

只需添加此样式 style="outline: none !important"到你的主分区。

<div class="modal fade bs-example-modal-sm vcenter" id="deleteconfirmation" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" style="outline: none !important">

蓝线将消失。
