如何更改Twitter Bootstrap模式框的默认宽度？ [英] How can I change the default width of a Twitter Bootstrap modal box?

问题描述

我尝试了以下内容：

   <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>

这个Javascript：

And this Javascript:

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

结果不是我的预期。模态左上方位于屏幕中央。

The result is not what I expected. The modal top left is positioned in the center of the screen.

任何人都可以帮助我。有没有人试过这个。我认为这不是一件不寻常的事情。

Can anyone help me. Has anyone else tried this. I assume it's not an unusual thing to want to do.

推荐答案

更新：

在 bootstrap 3 中，您需要更改模态对话框。
因此，在这种情况下，您可以在模态对话框的位置添加类 modal-admin 。

In bootstrap 3 you need to change the modal-dialog. So in this case you can add the class modal-admin in the place where modal-dialog stands.

原始答案（Bootstrap< 3）

是否确定你之所以想用JS / jQuery改变它吗？

Is there a certain reason you're trying to change it with JS/jQuery?

您可以使用CSS轻松完成，这意味着您无需在文档中进行样式设置。
在您自己的自定义CSS文件中，您添加：

You can easily do it with just CSS, which means you don't have to do your styling in the document. In your own custom CSS file, you add:

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

在您的情况下：

body .modal-admin {
    /* new custom width */
    width: 750px;
    /* must be half of the width, minus scrollbar on the left (30px) */
    margin-left: -375px;
}

我把身体放在选择器之前的原因是它需要更高的优先级比默认值。这样您就可以将其添加到自定义CSS文件中，而无需担心更新Bootstrap。

The reason I put body before the selector is so that it takes a higher priority than the default. This way you can add it to an custom CSS file, and without worries update Bootstrap.
