引导模态不起作用，但模态 SM 是

Question

我有一个我制作的引导模态-sm，但现在我想将其更改为具有更大宽度的正常模态。

当我删除类"modal-sm"并仅替换为"modal"时，背景仍然变暗，但实际的模态不显示。

如果我手动进入网络检查器并取消选中 .modal 上的"display：none"，我可以看到正确的模态弹出窗口。

任何想法为什么这不能像它应该的那样工作？

 <a href="#" data-toggle="modal" data-target=".modal-gallery-<?= $shoots[1]['id'] ?>">Buy Gallery</a>

<!-- MODALS -->
<div class="modal fade modal-gallery-<?= $shoots[1]['id'] ?> in" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
<div class="modal-dialog modal">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
        </div>
        <div class="modal-body downloads">
            <div class="buttons">
                <div class="form-group">
                    <h2>test</h2>
                </div>
            </div>
        </div>
    </div>
</div>
</div>

您需要从内部div中删除.modal-sm - 如：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap-theme.min.css">
<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<!-- Small modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">regular modal</button>
<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
<!-- remove modal-sm from here to get normal size -->
  <div class="modal-dialog"> 
    <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">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>Small size</p>
      </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><!-- /.modal-content -->
  </div>
</div>
