我如何改变Twitter引导模式框的默认宽度?

我尝试了以下方法:

   <div class="modal hide fade modal-admin" id="testModal" style="display: none;">
        <div class="modal-header">
          <a data-dismiss="modal" class="close">×</a>
          <h3 id='dialog-heading'></h3>
        </div>
        <div class="modal-body">
            <div id="dialog-data"></div>
        </div>
        <div class="modal-footer">
          <a data-dismiss="modal" class="btn" >Close</a>
          <a class="btn btn-primary" id="btnSaveChanges">Save changes</a>
        </div>
    </div>

这段Javascript:

    $('.modal-admin').css('width', '750px');
    $('.modal-admin').css('margin', '100px auto 100px auto');
    $('.modal-admin').modal('show')

结果不是我预料的那样。模态的左上角位于屏幕的中心。

有人能帮帮我吗?有人试过吗?我想这是一件很平常的事。

you can use any prefix or postfix name for modal. but you need to make sure that's should use everywhere with same prefix/postfix name.    

body .modal-nk {
        /* new custom width */
        width: 560px;
        /* must be half of the width, minus scrollbar on the left (30px) */
        margin-left: -280px;
    }

body .nk-modal {
            /* new custom width */
            width: 560px;
            /* must be half of the width, minus scrollbar on the left (30px) */
            margin-left: -280px;
        }

.Size(ModalSize.Large)

sample:
 using (var modal = Html.Bootstrap().Begin(new Modal().Id("modalProject_" + modelItem.id).Closeable().Size(ModalSize.Large)))
                {
}

保留响应式设计，将宽度设置为您想要的。

.modal-content {
  margin-left: auto;
  margin-right: auto;
  max-width: 360px;
}

保持简单。

对于Bootstrap 3，这里是如何做到这一点。

在HTML标记中添加一个模态范围样式(从Bootstrap 3文档中的示例改编而来)

<div class="modal fade modal-wide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 id="myModalLabel" class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</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><!-- /.modal-dialog -->
</div><!-- /.modal -->

并添加以下CSS

.modal-wide .modal-dialog {
  width: 80%; /* or whatever you wish */
}

现在不需要在Bootstrap 3中覆盖margin-left来让它居中。

如果你正在使用Bootstrap 3，你需要改变模态对话框div，而不是模态div，就像在接受的答案中显示的那样。此外，为了保持Bootstrap 3的响应性，使用媒体查询编写覆盖CSS是很重要的，这样在较小的设备上模式将是全宽的。

请参阅这个JSFiddle来尝试不同的宽度。

HTML

<div class="modal fade">
    <div class="modal-dialog custom-class">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h3 class="modal-header-text">Text</h3>
            </div>
            <div class="modal-body">
                This is some text.
            </div>
            <div class="modal-footer">
                This is some text.
            </div>
        </div><!-- /.modal-content -->
    </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

CSS

@media screen and (min-width: 768px) {
    .custom-class {
        width: 70%; /* either % (e.g. 60%) or px (400px) */
    }
}
